Question: What did Kennedy's aides think the speech would cause?
About the article "Assassination of Martin Luther King, Jr.", section "Robert F. Kennedy speech".

Candidate passages:
A speech on the assassination of Martin Luther King, Jr. was given on April 4, 1968, by New York Senator Robert F. Kennedy (who was himself assassinated two months later).
Kennedy was campaigning for the 1968 Democratic presidential nomination and had spoken at the University of Notre Dame and Ball State University earlier that day.
Before boarding a plane to fly to Indianapolis for one last campaign speech in a predominantly black neighborhood of the city he learned that Martin Luther King had been shot, leading Kennedy press secretary Frank Mankiewicz to suggest that he ask the audience to pray for the King family and ask them to follow King's deeply held belief in non-violence.
They did not learn that King was dead until they landed in Indianapolis.
Both Mankiewicz and speechwriter Adam Walinsky drafted notes immediately before the rally for Kennedy's use, but Kennedy refused Walinsky's notes, instead using some that he had likely written on the ride over; Mankiewicz arrived after Kennedy had already begun to speak.
Prior to arriving at the rally, the Chief of Police in Indianapolis told Kennedy that he could not provide protection and that giving the remarks would be too dangerous, but Kennedy decided to go ahead regardless.
Standing on a podium mounted on a flatbed truck, Kennedy spoke for just four minutes and fifty-seven seconds.
Robert F. Kennedy was the first to inform the audience of the death of Martin Luther King, causing some in the audience to scream and wail.
Several of Kennedy's aides were even worried that the delivery of this information would result in a riot.
Once the audience quieted down, Kennedy acknowledged that many in the audience would be filled with anger.
But then Kennedy went on: "For those of you who are black and are tempted to fill with -- be filled with hatred and mistrust of the injustice of such an act, against all white people, I would only say that I can also feel in my own heart the same kind of feeling.
I had a member of my family killed, but he was killed by a white man."
These remarks surprised Kennedy aides, who had never heard him speak publicly of John F. Kennedy's death.
Kennedy continued, saying that the country had to make an effort to "go beyond these rather difficult times," and then quoted a poem by the Greek playwright Aeschylus, on the theme of the wisdom that comes, against one's will, from pain.
To conclude, Kennedy said that the country needed and wanted unity between blacks and whites, asked the audience members to pray for the King family and the country, and once more quoted the ancient Greeks.
The speech was credited in part with preventing post-assassination rioting in Indianapolis where it was given, though there were riots in many other parts of the country.
It is widely considered one of the greatest speeches in American history.
As a young and outgoing urban Democrat, new to Washington, Rostenkowski quickly found mentors and made friends with other Democrats.
His relationship with Massachusetts Reps. Edward Boland and Torbert Macdonald as well as John F. Kennedy aides Lawrence O'Brien and Kenny O'Donnell led to his involvement in JFK's run for the White House.
In 1960 at the request of the Kennedy campaign he gave speeches in southern states for Kennedy.
Chicago voters turned out in large majority for Kennedy.
On September 26, 1960, Rostenkowski witnessed what many consider the turning point in Kennedy's battle with Richard Nixon.
Kennedy invited Rostenkowski to the CBS studios in downtown Chicago to view in person, the first ever televised Presidential debate.
Unaware of the two candidates' stark differences on camera, Rostenkowski later said “I was under the impression that Kennedy lost the debate.” (Cohen, 48)In the aftermath of Kennedy's assassination Rostenkowski was one of a small group who made regular visits to Jacqueline Kennedy's home in Georgetown.
"On a regular basis Kenny O'Donnell would get three or four of us from Capitol Hill, who worked with Jack Kennedy, together at Jackie's house.
We would sit around Jackie's living room with Bobby Kennedy eat sandwiches, have some drinks and tell war stories.
Jackie would laugh so hard her side would hurt sometimes.
(O'Donnell, 339) 
The Kennedy administration began its dealings with Canada badly, with Kennedy mispronouncing Diefenbaker's name in a press conference announcing the Prime Minister's visit to Washington in February 1961.
A furious Diefenbaker brought up in Cabinet whether to send a note of protest at the gaffe to Washington; his colleagues were inclined to let the matter pass.
When the two met in Washington on February 20, Diefenbaker was impressed by Kennedy, and invited him to visit Ottawa.
President Kennedy, however, told his aides that he never wanted "to see the boring son of a bitch again".
The Ottawa visit also began badly: at the welcome at the airport, Kennedy again mispronounced Diefenbaker's name and stated that after hearing the Prime Minister's (notoriously bad) French, he was uncertain if he should venture into the language (Kennedy's French was equally bad).
After meeting with Diefenbaker, Kennedy accidentally left behind a briefing note suggesting he "push" Diefenbaker on several issues, including the decision to accept nuclear weapons on Canadian soil, which bitterly divided the Cabinet.
Diefenbaker was also annoyed by Kennedy's speech to Parliament, in which he urged Canada to join the OAS (which Diefenbaker had already rejected), and by the President spending most of his time talking to Leader of the Opposition Pearson at the formal dinner.
Both Kennedy and his wife Jackie were bored by Diefenbaker's Churchill anecdotes at lunch, stories that Jackie Kennedy later described as "painful".
Diefenbaker was initially inclined to go along with Kennedy's request that nuclear weapons be stationed on Canadian soil as part of NORAD.
However, when an August 3, 1961, letter from Kennedy which urged this was leaked to the media, Diefenbaker was angered and withdrew his support.
The Prime Minister was also influenced by a massive demonstration against nuclear weapons, which took place on Parliament Hill.
Diefenbaker was handed a petition containing 142,000 names.
By 1962, the American government was becoming increasingly concerned at the lack of a commitment from Canada to take nuclear weapons.
The interceptors and Bomarc missiles with which Canada was being supplied as a NORAD member were either of no use or of greatly diminished utility without nuclear devices.
Canadian and American military officers launched a quiet campaign to make this known to the press, and to advocate for Canadian agreement to acquire the warheads.
Diefenbaker was also upset when Pearson was invited to the White House for a dinner for Nobel Prize winners in April, and met with the President privately for 40 minutes.
When the Prime Minister met with retiring American Ambassador Livingston Merchant, he angrily disclosed the paper Kennedy had left behind, and hinted that he might make use of it in the upcoming election campaign.
Merchant's report caused consternation in Washington, and the ambassador was sent back to see Diefenbaker again.
This time, he found Diefenbaker calm, and the Prime Minister pledged not to use the memo, and to give Merchant advance word if he changed his mind.
Canada appointed a new ambassador to Washington, Charles Ritchie, who on arrival received a cool reception from Kennedy and found that the squabble was affecting progress on a number of issues.
Though Kennedy was careful to avoid overt favouritism during the 1962 Canadian election campaign, he did allow his pollster, Lou Harris, to work clandestinely for the Liberals.
Several times during the campaign, Diefenbaker stated that the Kennedy administration desired his defeat because he refused to "bow down to Washington".
After Diefenbaker was returned with a minority, Washington continued to press for acceptance of nuclear arms, but Diefenbaker, faced with a split between Defence Minister Douglas Harkness and External Affairs Minister Howard Green on the question, continued to stall, hoping that time and events would invite consensus.
When the Cuban Missile Crisis erupted in October 1962, Kennedy chose not to consult with Diefenbaker before making decisions on what actions to take.
The US President sent former Ambassador Merchant to Ottawa to inform the Prime Minister as to the content of the speech that Kennedy was to make on television.
Diefenbaker was upset at both the lack of consultation and the fact that he was given less than two hours advance word.
He was angered again when the US government released a statement stating that it had Canada's full support.
In a statement to the Commons, Diefenbaker proposed sending representatives of neutral nations to Cuba to verify the American allegations, which Washington took to mean that he was questioning Kennedy's word.
When American forces went to a heightened alert, DEFCON 3, Diefenbaker was slow to order Canadian forces to match it.
Harkness and the Chiefs of Staff had Canadian forces clandestinely go to that alert status anyway, and Diefenbaker eventually authorized it.
The crisis ended without war, and polls found that Kennedy's actions were widely supported by Canadians.
Diefenbaker was severely criticized in the media. 
After Johnson's withdrawal, Vice- President Hubert Humphrey announced his candidacy.
Kennedy was successful in four state primaries (Indiana, Nebraska, South Dakota, and California) and McCarthy won six (Wisconsin, Pennsylvania, Massachusetts, Oregon, New Jersey, and Illinois).
However, in primaries where they campaigned directly against one another, Kennedy won three primaries (Indiana, Nebraska, and California) and McCarthy won one (Oregon).
Humphrey did not compete in the primaries, leaving that job to favorite sons who were his surrogates, notably Senator George A. Smathers from Florida, Senator Stephen M. Young from Ohio, and Governor Roger D. Branigin of Indiana.
Instead, Humphrey concentrated on winning the delegates in non-primary states, where party leaders such as Chicago Mayor Richard J. Daley controlled the delegate votes in their states.
Kennedy defeated Branigin and McCarthy in the Indiana primary, and then defeated McCarthy in the Nebraska primary.
However, McCarthy upset Kennedy in the Oregon primary.
After Kennedy's defeat in Oregon, the California primary was seen as crucial to both Kennedy and McCarthy.
McCarthy stumped the state's many colleges and universities, where he was treated as a hero for being the first presidential candidate to oppose the war.
Kennedy campaigned in the ghettos and barrios of the state's larger cities, where he was mobbed by enthusiastic supporters.
Kennedy and McCarthy engaged in a television debate a few days before the primary; it was generally considered a draw.
On June 4, Kennedy narrowly defeated McCarthy in California, 46%–42%.
However, McCarthy refused to withdraw from the race and made it clear that he would contest Kennedy in the upcoming New York primary, where McCarthy had much support from anti-war activists in New York City.
The New York primary quickly became a moot point, however, for in the early morning of June 5, Kennedy was shot shortly after midnight; he died twenty-six hours later.
Kennedy had just given his victory speech in a crowded ballroom of the Ambassador Hotel in Los Angeles; he and his aides then entered a narrow kitchen pantry on their way to a banquet room to meet with reporters.
In the pantry Kennedy and five others were shot by Sirhan Sirhan, a Christian Palestinian who hated Kennedy because of his support for Israel.
Sirhan admitted his guilt, was convicted of murder, and is still in prison.
In recent years some have cast a doubt on this, including Sirhan himself, who said he was "brainwashed" into killing Kennedy and was a patsy.
Political historians have debated to this day whether Kennedy could have won the Democratic nomination had he lived.
Some historians, such as Theodore H. White and Arthur M. Schlesinger, Jr., have argued that Kennedy's broad appeal and famed charisma would have convinced the party bosses at the Democratic Convention to give him the nomination.
Jack Newfield, author of "RFK: A Memoir", stated in a 1998 interview that on the night he was assassinated, "had a phone conversation with Mayor Daley of Chicago, and Mayor Daley all but promised to throw the Illinois delegates to Bobby at the convention in August 1968.
I think he said to me, and Pete Hamill, 'Daley is the ball game, and I think we have Daley.
However, other writers such as Tom Wicker, who covered the Kennedy campaign for "The New York Times", believe that Humphrey's large lead in delegate votes from non-primary states, combined with Senator McCarthy's refusal to quit the race, would have prevented Kennedy from ever winning a majority at the Democratic Convention, and that Humphrey would have been the Democratic nominee even if Kennedy had lived.
The journalist Richard Reeves and historian Michael Beschloss have both written that Humphrey was the likely nominee, and future Democratic National Committee chairman Larry O'Brien wrote in his memoirs that Kennedy's chances of winning the nomination had been slim, even after his win in California.
At the moment of RFK's death, the delegate totals were: Hubert Humphrey 561 Robert F. Kennedy 393 Eugene McCarthy 258 Total popular vote:  Eugene McCarthy: 2,914,933 (38.73%)  Robert F. Kennedy: 2,305,148 (30.63%)  Stephen M. Young: 549,140 (7.30%)  Lyndon B. Johnson: 383,590 (5.10%)  Thomas C. Lynch: 380,286 (5.05%)  Roger D. Branigin: 238,700 (3.17%)  George Smathers: 236,242 (3.14%)  Hubert Humphrey: 166,463 (2.21%)  Unpledged: 161,143 (2.14%)  Scott Kelly: 128,899 (1.71%)  George Wallace: 34,489 (0.46%)  Richard Nixon (write-in): 13,610 (0.18%)  Ronald Reagan (write-in): 5,309 (0.07%)  Ted Kennedy: 4,052 (0.05%)  Paul C. Fisher: 506 (0.01%)  John G. Crommelin: 186 (0.00%)  
Kennedy was the first to publicly inform the audience of King's assassination, causing members of the audience to scream and wail in disbelief.
Several of Kennedy's aides were worried that the delivery of this information would result in a riot.
Once the audience quieted down, Kennedy spoke of the threat of disillusion and divisiveness at King's death and reminded the audience of King's efforts to "replace that violence, that stain of bloodshed that has spread across our land, with an effort to understand with compassion and love."
Kennedy acknowledged that many in the audience would be filled with anger, especially since the assassin was believed to be a white man.
He empathized with the audience by referring to the assassination of his brother, President John F. Kennedy, by a white man.
The remarks surprised Kennedy aides, who had never heard him speak of his brother's death in public.
Quoting the ancient Greek playwright Aeschylus, whom he had discovered through his brother's widow, Jacqueline Kennedy, Kennedy said, "Even in our sleep, pain which cannot forget falls drop by drop upon the heart until, in our own despair, against our will, comes wisdom through the awful grace of God."
Kennedy then delivered one of his most well-remembered remarks: "What we need in the United States is not division; what we need in the United States is not hatred; what we need in the United States is not violence or lawlessness, but love and wisdom, and compassion toward one another, and a feeling of justice towards those who still suffer within our country, whether they be white or whether they be black."
To conclude, Kennedy reiterated his belief that the country needed and wanted unity between blacks and whites and encouraged the country to "dedicate ourselves to what the Greeks wrote so many years ago: to tame the savageness of man and to make gentle the life of this world."
He finished by asking the audience members to pray for "our country and our people."
Rather than exploding in anger at the tragic news of King's death, the crowd dispersed quietly.
