Former FBI Director James Comey says Acting Attorney General Matthew Whitaker �may not be the sharpest knife� in the drawer.

Comey made those comments during an interview Monday with WGBH News in Boston after he was asked whether Whitaker could derail special counsel Robert Mueller�s Russia investigation.

Comey said Whitaker �may not be the sharpest knife in our drawer� but Comey said Whitaker �knows that if he acted in an extralegal way, he would go down in history for the wrong reasons.�

Comey also said his legal team is reviewing his options after he was subpoenaed to appear before a congressional committee next week. Comey has said he wants the questioning to happen publicly.

A Department of Justice spokeswoman didn�t immediately respond to an email Tuesday.
