Picked who?
If Trump had a problem with Democrat attorneys on the Mueller Probe, why did he nominate Christopher Wray who worked under James Comey?

“Wray was Assistant Attorney General from 2003 to 2005, working under Deputy Attorney General James Comey. While heading the Criminal Division, Wray oversaw prominent fraud investigations, including Enron.[15][19] In a May 30, 2013 Washingtonian.com article, Garrett M. Graff revealed that Wray was one of the senior Justice Dept officials that nearly resigned in 2004, alongside then FBI Director Robert Mueller and Deputy Attorney General James Comey, due to illegal surveillance techniques the Bush administration had put in place under the Terrorist Surveillance Program.”
