ALEXANDRIA, Va. (AP) — President Donald Trump says his attorney general should put an end to special counsel Robert Mueller’s Russia investigation.

Trump is making his views known in a series of tweets as the trial of his onetime campaign chairman, Paul Manafort, enters its second day in a Virginia courtroom. He’s on trial for bank fraud and tax evasion charges.

The president says Attorney General Jeff Sessions “should stop this Rigged Witch Hunt right now, before it continues to stain our country any further.”

But Sessions stepped aside last year from overseeing Mueller’s inquiry, and it’s Deputy Attorney General Rod Rosenstein who’s taken over that duty.

Trump is trying to distance himself from Manafort, who led Trump’s efforts to secure the GOP presidential nomination in 2016. Trump tweets that Manafort “He worked for me for a very short time.”

Manafort was the campaign chairman for about five months in 2016.
