Mark Corallo had represented Trump's outside lawyers amid the federal and congressional Russia inquiries until he resigned last summer, after revelations about a June 2016 meeting between Trump's son Donald Jr and a group of Russians. This would, since Attorney General Jeff Sessions had correctly recused himself from any oversight of the Mueller investigation, given Trump more control over the investigation.
The discussions about presidential testimony are ongoing and professional, says one source.
Now that multiple news agencies have confirmed that President Trump moved last June to fire Special Counsel Robert Mueller, Congress must act improve the counsel law.

"While the president is not expected to address the Russian Federation investigation in tonight's State of the Union, CNN has learned that Trump has grown increasingly impatient with the special counsel's office", Acosta said. Moscow has denied interference and Trump, a Republican, has said there was no collusion.
The cache of documents turned over to Mueller also includes internal communications regarding the firing of Comey, an episode that includes Sessions, Deputy Attorney General Rod Rosenstein and the White House. "This guy is a street fighter and he thinks this Mueller investigation is B.S".
Corallo did not want to engage in or be associated with White House attacks on Mueller and top Justice Department officials, according to a person familiar with the matter.
McGahn's closeness to each of these events has made him a person of interest in the Mueller investigation, and the White House lawyer was questioned by Mueller's team in early December, just hours before former National Security Adviser Michael Flynn was charged with lying to the FBI. It remains to be seen whether he will continue to do so once Trump is called before Mueller's probe in the next several weeks.
