John Dowd, the veteran attorney leading President Trump's outside legal team, has tendered his resignation.
He declined to explain why he was leaving the team that is helping the president deal with Robert Mueller's special counsel investigation.
"I love the president and wish him well," Dowd said when reached on his cellphone by NPR.
The New York Times reported — and Dowd would not confirm — that he is leaving because the president was "increasingly ignoring his advice."
Trump's legal team is in the midst of ongoing discussions with Mueller over a possible interview with President Trump. Dowd recently described them as "productive and constructive." Speaking at a White House event Thursday after news of the resignation broke, the president told reporters he would like to speak to investigators as part of the Mueller probe.
Over the weekend, however, Dowd suggested that the Mueller investigation be shut down. At first, he said he was speaking as the president's counsel; then he walked it back to say he was speaking for himself.
"Just end it on the merits in light of recent revelations," Dowd said in an email.
Those recent revelations?
"I pray that Acting Attorney General Rosenstein will follow the brilliant and courageous example of the FBI Office of Professional Responsibility and Attorney General Jeff Sessions and bring an end to alleged Russia Collusion investigation manufactured by McCabe's boss James Comey based upon a fraudulent and corrupt Dossier," Dowd emailed.
Hours later, President Trump began tweeting his own criticisms of the investigation, using Mueller's name for the first time:
Dowd's resignation also comes just days after the president added a new lawyer to the team, Joe diGenova, who has been outspoken in his attacks on the Justice Department Russia investigation.
"There was a brazen plot to illegally exonerate Hillary Clinton and — if she didn't win the election — to then frame Donald Trump with a falsely created crime," diGenova said on Fox News in January.
Dowd was reportedly blindsided by the hire.
Dowd had only just been brought onto Trump's legal team last June to add some Washington experience to Trump's defense. Here's the thumbnail of Dowd's career we wrote up back then:
John Dowd is best known as the author of the Dowd Report, which led to Pete Rose's lifetime ban from baseball for gambling on the game.
"I'm very, very happy and very proud of the commissioner of baseball for protecting the game," Dowd told NPR two years ago, when Major League Baseball denied Rose's request to be reinstated. "In this day and age, protecting the integrity of anything is a big deal."
In 2011, Dowd represented Raj Rajaratnam in a major insider-trading case. Rajaratnam was convicted on all counts and walking out of the courtroom Dowd offered some choice words to a CNBC reporter, flipping off the camera.

But more to the point, Dowd is a seasoned Washington hand who represented Sen. John McCain, R-Ariz., in the Keating Five scandal (McCain was cleared) and helped a retired Air Force colonel get immunity to testify in the Iran Contra scandal.
That's experience that would be quite valuable if the president is in fact being investigated for obstruction of justice by the special counsel.
