President Barack Obama cautioned Donald J. Trump against procuring Michael T. Flynn to be a piece of his national security group when Mr. Obama met with his successor in the Oval Office two days after the November race, two former Obama administration officials said on Monday.
Mr. Obama, who had fired Mr. Flynn as the head of the Defense Intelligence Agency, told Mr. Trump that he would have significant concerns about Mr. Flynn turning into a top national security assistant, said the administration officials, who were advised on the Oval Office discussion. Mr. Trump later ignored the advice, naming Mr. Flynn to be his national security adviser.
Mr. Flynn was constrained out of that position after it was revealed that he had misled Vice President Mike Pence about his discussions with the Russian diplomat to the United States, in the midst of a proceeding with examination concerning associations between the Russian government and the Trump campaign.
Mr. Obama and Mr. Trump met without precedent for the Oval Office on Nov. 10 in what both men later depicted as an agreeable, hour and a half session in which the active president vowed to do all that he could to bolster the move to a new administration.
Mr. Flynn’s name came up during a broader discussion about personnel issues, the former administration officials said. Mr. Obama’s concerns about Mr. Flynn, which were first revealed by NBC News, were largely about his management of the D.I.A. furthermore, originated before the later worries about his contacts with the Russian ambassador, Sergey I. Kislyak.
In any case, one of the previous organization authorities said that Mr. Obama was likewise mindful of Mr. Flynn’s all around exposed outing in 2015 to Moscow and different contacts with Russia.
The disclosure on Monday about Mr. Obama’s notice came hours before Sally Q. Yates, the former acting attorney general, was booked to affirm toward the evening before a Senate board that she later raised her particular worries about Mr. Flynn’s Russia contacts with the incoming Trump administration.
Mr. Trump censured Obama authorities on Monday, saying in two Twitter messages that it was his ancestor’s organization that gave Mr. Flynn a security clearance.
“General Flynn was given the highest security clearance by the Obama Administration — but the Fake News seldom likes talking about that,” Mr. Trump said.
In a second Twitter message, Mr. Trump added: “Ask Sally Yates, under oath, if she knows how the classified information got into the newspapers soon after she explained it to W.H. Counsel.” An early version of the message misspelled “counsel.”
