Dershowitz: Trump Better Off Challenging a Subpoena Over Sitting Down With Mueller

Watters: Mueller Is Trying to 'Criminalize the Exercise of Presidential Power'

Fox News senior judicial analyst Judge Andrew Napolitano said Wednesday's shakeup on President Trump's legal team is a sign that Trump finally realizes the seriousness of Special Counsel Robert Mueller's investigation.

Attorney Ty Cobb is set to leave Trump's in-house legal team and will be replaced by Emmet Flood, who defended former President Bill Clinton during his impeachment.

On "Outnumbered Overtime," Napolitano said Flood is a top-of-the-line, brilliant litigator, although this is very late in the game for a change of this magnitude.

"There is no one on the president's team who's been there since day one. And with the departure of Ty Cobb, there will be no one on the president's team who's personally familiar with the hundreds of thousands of pages of documents that the president has surrendered to the special counsel," Napolitano said.

He noted that Trump has two separate legal teams, one to defend Trump the person -- which Rudy Giuliani was recently hired to lead -- and one to defend the presidency -- which Flood is joining onto.

Flood is expected to replace Cobb as a liaison between the White House and Mueller’s office, which is conducting an investigation into allegations of collusion between the Trump campaign and Russian officials ahead of the 2016 election.

"This also tells me that the president finally recognizes how serious the Mueller probe is," Napolitano said. "These are not only two well-known lawyers -- Rudy better know to the public, Emmet better know to the legal community -- they are top-shelf, very gifted, very experienced lawyers."

"He has that on his team now for the first time in 15 months."
