WASHINGTON — Intelligence officials warned House lawmakers last week that Russia was interfering in the 2020 campaign to try to get President Trump re-elected, five people familiar with the matter said, in a disclosure that angered Mr. Trump, who complained that Democrats would use it against him.
The day after the Feb. 13 briefing to lawmakers, Mr. Trump berated Joseph Maguire, the outgoing acting director of national intelligence, for allowing it to take place, people familiar with the exchange said. Mr. Trump cited the presence in the briefing of Representative Adam B. Schiff, the California Democrat who led the impeachment proceedings against him, as a particular irritant.
During the briefing to the House Intelligence Committee, Mr. Trump’s allies challenged the conclusions, arguing that Mr. Trump has been tough on Russia and strengthened European security. Some intelligence officials viewed the briefing as a tactical error, saying that had the official who delivered the conclusion spoken less pointedly or left it out, they would have avoided angering the Republicans.
That intelligence official, Shelby Pierson, is an aide to Mr. Maguire who has a reputation of delivering intelligence in somewhat blunt terms. The president announced on Wednesday that he was replacing Mr. Maguire with Richard Grenell, the ambassador to Germany and long an aggressively vocal Trump supporter.
Though some current and former officials speculated that the briefing may have played a role in the removal of Mr. Maguire, who had told people in recent days that he believed he would remain in the job, two administration officials said the timing was coincidental. Mr. Grenell had been in discussions with the administration about taking on new roles, they said, and Mr. Trump had never felt a personal kinship with Mr. Maguire.
Spokeswomen for the Office of the Director of National Intelligence and its election security office declined to comment. A White House spokesman did not immediately respond to requests for comment.
A House intelligence committee official called the Feb. 13 briefing an important update about “the integrity of our upcoming elections” and said that members of both parties attended, including Representative Devin Nunes of California, the top Republican on the committee.
