The Latest on President Donald Trump and his tweets about the FBI (all times local):

President Donald Trump is again questioning the impartiality of the deputy director of the FBI, Andrew McCabe, who is planning to retire from the bureau in the months ahead after being buffeted by attacks over alleged anti-Trump bias in the agency.

In a tweet Saturday, the president wrote: "How can FBI Deputy Director Andrew McCabe, the man in charge, along with leakin' James Comey, of the Phony Hillary Clinton investigation (including her 33,000 illegally deleted emails) be given $700,000 for wife's campaign by Clinton Puppets during investigation?"

McCabe spent hours behind closed doors on Capitol Hill this week being grilled by lawmakers on two separate committees. The appearances came as part of a new investigation of the FBI and its 2016 inquiry into Clinton's email practices when she was secretary of state. McCabe's role supervising the email investigation has come under renewed scrutiny.

McCabe's wife, Jill, received $700,000 in donations from Virginia Gov. Terry McAuliffe's political action committee and the Virginia Democratic Party for a state Senate race in 2015. The money was donated before McCabe was promoted to deputy director and assumed a supervisory role in the Clinton email investigation.
