Washington (CNN) Attorney General Jeff Sessions dodged questions Tuesday over whether President Donald Trump has pressured him to resign amid Trump's relentless criticism during his tenure leading the Justice Department.

Sessions acknowledged that Trump has been "frustrated with him," but said he is "honored" to head the Justice Department and "will do so as long as appropriate for me to do so."

"The President speaks his mind. He says what's on his mind at the time. And he's been frustrated about my recusal and other matters. But we have been so pleased and honored to be given the responsibility to execute his agenda at the Department of Justice," Sessions said.

Trump has repeatedly criticized Sessions for his decision to recuse himself from investigations related to the 2016 Trump presidential campaign, which include the special counsel probe into Russian interference in the election.
