Attorney General William P. Barr has held private meetings overseas with foreign intelligence officials seeking their help in a Justice Department inquiry that President Trump hopes will discredit U.S. intelligence agencies’ examination of possible connections between Russia and members of the Trump campaign during the 2016 election, according to people familiar with the matter.

Special counsel Robert S. Mueller III wrote a letter in late March complaining to Attorney General William P. Barr that a four-page memo to Congress describing the principal conclusions of the investigation into President Trump “did not fully capture the context, nature, and substance” of Mueller’s work, according to a copy of the letter reviewed Tuesday by The Washington Post.

Memos written by Andrew McCabe, then the acting FBI director, say deputy attorney general Rod J. Rosenstein suggested he secretly record his talks with President Trump, and that Rosenstein discussed possibly trying to remove him from office, according to people familiar with the matter.

President Trump’s former lawyer Michael Cohen pleaded guilty Tuesday in a Manhattan courthouse to eight violations of banking, tax and campaign finance laws in a federal investigation that scrutinized his business dealings and efforts to silence women with negative stories about Trump.

The head of the research firm behind a dossier of allegations against Donald Trump told congressional investigators that someone inside Trump’s network had also provided the  FBI with information during the 2016 campaign. It was released by the ranking Democrat on the Senate Judiciary Committee, Sen. Dianne Feinstein of California. Feinstein said she released the transcript to set the record straight. “The innuendo and misinformation circulating about the transcript are part of a deeply troubling effort to undermine the investigation into potential collusion and obstruction of justice,’’ she said.

The move by special counsel Robert S. Mueller III to investigate Trump’s conduct marks a major turning point in the nearly year-old FBI investigation, which until recently focused on Russian meddling during the presidential campaign and on whether there was any coordination between the Trump campaign and the Kremlin. Investigators have also been looking for any evidence of possible financial crimes among Trump associates.
