Example Input: Justice Department special counsel Robert Mueller broke his own record this week for guilty pleas. On Tuesday  Dutch attorney Alex van der Zwaan appeared in federal court and admitted he had lied to investigators about his contacts with  Donald Trump's former campaign vice chairman  Rick Gates .
On Friday   Gates himself  appeared before a federal judge and confirmed that  he  is changing  his  plea to guilty.  He  had been fighting the case brought against  him  and the former Trump campaign chairman  Paul Manafort  which alleged they laundered millions of dollars and broke other laws related to their work for clients in Ukraine.
 Gates  and Manafort have not been charged with conspiracy to defraud the U.S. by "impairing  obstructing and defeating the lawful functions of the government through fraud and deceit for the purpose of interfering with the U.S. political and electoral processes." That was the charge Mueller leveled at 13 Russians and three Russian companies he says did interfere with the election.
Or the special counsel's office could be laying down one brick in a larger structure. At the very least   Gates'  future testimony against  his  longtime business partner raises the likelihood that Manafort could be convicted of some or all of the charges  he  continues fighting.
Manafort and his lawyers know this. So one of Mueller's strategies in getting  Gates  to turn state's evidence might be to persuade Manafort to do the same and tell what he knows about other people in the Trump campaign orbit.
Or evidence from  Gates  might be what the special counsel's office needs to build a case against Manafort for conspiring in the 2016 Russian interference effort. Or  after years of working with Manafort   Gates  might have other evidence that would permit Mueller to bring new charges against Manafort.
Mueller announced a new indictment in Manafort's case on Friday evening. After  Gates  appeared in federal court Friday to enter his plea  Manafort continued to maintain his innocence and said he remained committed "to defend myself against the untrue piled up charges contained in the indictments against me."

Example Input: Could a small force of American soldiers have prevented Iraq from sliding back into chaos , as Governor Bush claims ? 
The exchange started like this : at the end of Jeb Bush 's town-hall meeting in Reno , Nevada , on Wednesday , a college student named Ivy Ziedrich stood up and said that she had heard Bush blame the growth of ISIS on President Obama , in particular on his decision to withdraw American troops from Iraq in 2011 . 
The origins of ISIS , Ziedrich said , lay in the decision by Bush 's brother , in 2003 , to disband the Iraqi Army following the toppling of Saddam Hussein 's government . 
Wow ," Bush said . 
Here is what happened : In 2003 , the U.S. military , on orders of President Bush , invaded Iraq , and nineteen days later threw out Saddam 's government . 
Historians -- along with Governor Bush and Ivy Ziedrich -- will be arguing about the question for a long time . 
"All right ," Bush said . 
Bush Administration officials involved in the decision -- like Paul Bremer and Walter Slocombe -- argued that they were effectively ratifying the reality that the Iraqi Army had already disintegrated . 
But the Bush White House went ahead . 
While it 's true that George W. Bush took actions that helped enable the creation of the Iraqi insurgency , and that some leaders of the insurgency formed ISIS , it 's not true that he "created" ISIS . 
And there 's a good argument to be made that an insurgency would have formed following the invasion of Iraq even if President Bush had kept the Iraqi Army together . 
Indeed , by 2011 the situation in Iraq -- as former Governor Bush said -- was relatively stable . 
But let 's get to Governor Bush 's assertion -- that Iraq went down the tubes because of President Obama 's decision to pull out all American forces , and that Obama could easily have left behind a residual force that would have kept the peace . 
"When we left Iraq , security had been arranged ," Bush said . 
A few days after that , President Bush or someone in his Administration decreed the dissolution of the Iraqi Army . 
Bush did n't like it : he offered a retort and then left the stage . 
So , on this , Governor Bush is n't entirely accurate , but makes a good point : the Obama Administration might have been able to keep some forces in Iraq if it had really tried .
Example Output: George W Bush

Example Input: âWeâre seeing the worst of it right now â said  Randy Bergen  a pediatrician who is leading the anti-flu effort for Kaiser Permanente Northern California . âWeâre really in historic territory  and I just donât know when itâs going to stop.â
The influenza A subtype H3N2 that appears to be most prevalent this year is particularly nasty  with more-severe symptoms including fever and body aches. Australia â whose experience U.S. public health officials follow closely in making their flu forecasts  in part because Australiaâs winter is our summer â reported a record-high number of confirmed flu cases in 2017. Another influenza B virus subtype also is circulating  âand thatâs no fun  either â  Bergen  said.
âSome protection is better than no protection â  Bergen  said  âbut itâs certainly disappointing to have a vaccine thatâs just not as effective as weâd like it to be.â
If you are sick  cover your cough and stay home from work if you can   Bergen  said. Remaining hydrated  eating nutritious foods and exercising can also help strengthen your immune system.
The hallmarks of flu are fever and body aches that accompany cough and congestion   Bergen  said.
Kaiser Permanente doctors are now being advised to prescribe antiviral drugs such as Tamiflu â given as a pill or  for children  an oral suspension â even without a lab test for influenza   Bergen  said. According to a report in the Los Angeles Times  however  Tamiflu supplies are running low.
And  Bergen  cautioned that these medications are only partly effective  reducing the length of illness by just a day or two.
