John Dowd - a top attorney on President Trump's personal legal team who said it's time for the Russian Federation collusion probe to end - has resigned from the president's personal legal team, CBS News has confirmed.
Other reports say Mr Trump had lost confidence in Mr Dowd's ability to handle special counsel Robert Mueller.
But just Saturday Dowd appeared to depart from that course of cooperation when he called on Deputy Attorney General Rod Rosenstein, who oversees Mueller's inquiry at the Justice Department, to "bring an end to the alleged Russian Federation collusion investigation".
Dowd first said he was speaking for the president but then rowed back, telling outlets including the Guardian he had spoken in a personal capacity.
Jay Sekulow, another of Trump's lawyers, praised Dowd in a statement: "John Dowd is a friend and has been a valuable member of our legal team". Comey's firing reportedly is a subject of interest to the special counsel's team.
Dowd's resignation also came after the president appointed former U.S. Attorney Joseph diGenova to his legal team.
DiGenova in particular has raised eyebrows for his claims on the Fox News Channel that the Justice Department and the Federal Bureau of Investigation framed Trump with manufactured evidence in an effort to help Hillary Clinton in 2016.
Kasowitz had long recommended that Trump take a more aggressive posture toward the Mueller investigation.
The head of President Donald Trump's legal team fighting against the special counsel's investigation quit Thursday after months of speculation about a possible shakeup to the team.
Dowd's remarks were a prelude to a series of recent tweets from Trump, who has called on Mueller directly to shutter the inquiry, repeatedly referring to the investigation as a "witch hunt".
Sekulow's role had been public communications on behalf of the Trump legal team.
Trump said on Friday that he was still willing to be interviewed by Mueller despite Dowd leaving. This stance puts them at odds with Trump, although Trump has been quick to dismiss reports of conflict.
He wrote the tweet about a New York Times story that said he was in discussions to hire veteran lawyer Emmet Flood, who represented Bill Clinton during the impeachment process.
This is at least the second major reshuffling of Trump's legal team in the past year.
In a written statement to the media, Dowd did not indicate why he left.
