(CNN) President Donald Trump has a longtime habit in high-profile meetings that's no "Art of the Deal" secret: a casual drop-by from daughter Ivanka Trump.
Take Wednesday's meeting with congressional leaders:  Ivanka Trump   who also serves as a White House adviser  "entered the Oval Office to 'say hello' and the meeting careened off-topic " a congressional source briefed on the meeting told CNN's Deirdre Walsh.
Some Republican leaders were "visibly annoyed by  Ivanka 's presence " the source said.
Marc Short  White House director of legislative affairs  confirmed the purpose of  Ivanka Trump's  visit.
"We asked  Ivanka  to briefly join the meeting for an update on the child care tax credit and how we are working to make tax reform a bipartisan issue " he said. "It was a quick and productive conversation."

  Ivanka Trump  also joined  her  father Wednesday afternoon in North Dakota  where  he  gave a tax reform speech.
In the middle of  his  remarks  the President brought  her  onstage.
"By the way   Ivanka Trump ? Everybody loves  Ivanka Trump  "  he  said. "Come on  should I bring Ivanka up?
 He  added that  his  daughter had asked to join  him  on the trip.
 Ivanka Trump  made brief remarks on stage before leaving the stage.
While  Trump  was speaking to The New York Times in July   Ivanka Trump  and daughter Arabella Kushner popped in to say "hello" as  he  was answering a question about former FBI Director James Comey's testimony on Capitol Hill.
" His  testimony is loaded up with lies  OK? But people didn't -- we had a couple people that said -- 'Hi baby  how are you?' "  Trump  said as  his  granddaughter entered the room.
"Just wanted to come say 'hi ' "  Ivanka Trump  said as  she  stood in the doorway  according to a transcript of the interview.
 The President  asked  his  granddaughter to say hello to the reporters in Mandarin  touting the six-year-old's "good  smart genes " before returning to the topic at hand.
Later that month   Ivanka Trump  dropped by an interview  the President  was having with The Wall Street Journal.
The 'Ivanka drop

Comic strip artist Mort Walker  a World War II veteran who satirized the Army and tickled millions of newspaper readers with the antics of the lazy private "Beetle Bailey " died Saturday.  He  was 94.
 Walker  died at  his  home in Stamford  Connecticut  said Greg Walker  his eldest son and a collaborator. His father's advanced age was the cause of death  he said.
 Walker  began publishing cartoons at age 11 and was involved with more than a half-dozen comic strips in  his  career  including "Hi and Lois " ''Boner's Ark" and "Sam & Silo." But  he  found  his  greatest success drawing slacker Beetle   his  hot-tempered sergeant and the rest of the gang at fictional Camp Swampy for nearly 70 years.
The character that was to become  Beetle Bailey  made  his  debut as Spider in  Walker 's cartoons published by the Saturday Evening Post in the late 1940s.  Walker  changed Spider's name and launched  "Beetle Bailey"  as a college humor strip in 1950.
At first the strip failed to attract readers and King Features Syndicate considered dropping it after just six months   Walker  said in a 2000 interview with The Associated Press. The syndicate suggested  Beetle  join the Army after the start of the Korean War   Walker  said.
"I was kind of against it because after World War II  Bill Mauldin and Sad Sack were fading away " he said. But his misgivings were overcome and  Beetle  "enlisted" in 1951.
 Walker  attributed the success of the strip to Beetle's indolence and reluctance to follow authority.
"Most people are sort of against authority "  he  said. "Here's  Beetle  always challenging authority. I think people relate to it."
 "Beetle Bailey"  led to spin-off comic strip "Hi and Lois " which  he  created with Dik Browne  in 1954. The premise was that  Beetle  went home on furlough to visit  his  sister Lois and brother-in-law Hi.
Fellow cartoonists remembered  Walker  on Saturday as a pleasant man who adored his fans. Bill Morrison  president of the National Cartoonists Society  called  Walker  the definition of "cartoonist" in a post on the society's website.
" He  lived and breathed the art every day of  his  life.  He  will be sorely missed by  his  friends in the NCS and by a world of comic strip fans " Morrison said.
Fellow cartoonist Mark Evanier said on his website that  Walker  was "delightful to be around and always willing to draw  Beetle  or Sarge for any of his fans. He sure had a lot of them."
"Beetle Bailey " which appeared in as many as 1 800 newspapers  sometimes sparked controversy. The Tokyo editions of the military newspaper Stars & Stripes dropped it in 1954 for fear that it would encourage disrespect of its officers. But ensuing media coverage spurred more than 100 newspapers to add the strip.
Shortly after President Bill Clinton took office   Walker  drew a strip suggesting that the draft be retroactive in order to send Clinton to Vietnam.  Walker  said  he  received hundreds of angry letters from Clinton supporters.
For years   Walker  drew Camp Swampy's highest-ranking officer  Gen. Amos Halftrack  ogling his secretary  Miss Buxley. Feminist groups claimed the strip made light of sexual harassment  and  Walker  said the syndicate wanted  him  to write out the lecherous general.
That wasn't feasible because the general was such a fixture in the strip   Greg Walker  said Saturday.  His  father solved the problem in 1997 by sending Halftrack to sensitivity training.

Choi Soon-sil  a confidante of Park  was convicted of receiving bribes from South Korean conglomerates including Samsung  the worldâs biggest maker of smartphones and semiconductors  and the Lotte Group.
Prosecutors had sought a four-year jail term for Shin  accusing Lotte of giving a foundation backed by Park and  Choi  7 billion won ($6.46 million) for favours such as a duty free store license.
Kim  the judge  said Park âabandoned constitutionally-given responsibility and gave position and power to othersâ and that  Choi  used her position âto monopolize state business and seek personal gainâ.
Prosecutors had demanded a 25-year jail term for  Choi  on charges including coercion  bribery  influence-peddling and abuse of authority.
Lee had been charged with giving some of the bribes that  Choi  was accused of receiving. However  last weekâs ruling said Leeâs bribe-giving was a âpassive compliance to political power â appearing to put the weight of the blame on Park and  Choi .
