Ty Cobb, the White House lawyer who had acted as the liaison between Robert Mueller’s special counsel and Donald Trump, has officially stepped down. To replace him, Trump has chosen Emmet Flood, the attorney who served as special counsel under George H.W. Bush and represented Bill Clinton during his impeachment. Flood was also Hillary Clinton’s lawyer during the whole Clinton email controversy.

According to the New York Times, we can expect Flood to take a much more hardline approach to Robert Mueller. This would be a far cry from Cobb, who had urged Trump to cooperate more with the special investigation. The Times also says that Flood is very highly regarded by conservative lawyers and judges, including Abbe Lowell, lawyer to Trump’s son-in-law, Jared Kushner. He has “connections with key players that could make him more effective than his predecessors on the legal team, including a good relationship with Donald F. McGahn II, the White House counsel.”

Others speculate that Flood’s appointment has everything to do with the special investigation. Reports from the Washington Post say that Trump may have wanted to have a loyal lawyer by his side in the face of Mueller’s initiative to subpoena him.

Politico reports that White House Press Secretary Sarah Huckabee Sanders welcomes the prospect of working with Flood since she believes he will aid in their battle against the special counsel, or the “Russia witch hunt.”
