Attorney General Jeff Sessions told the Senate Judiciary Committee Wednesday that while he would not assert executive privilege related to his private conversations with President Trump, he would still not describe those questions.

"I can neither assert executive privilege now, nor can I disclose today my confidential conversations with the president," Sessions told the Senate Judiciary Committee in his opening statement during a routine oversight hearing of the Department of Justice.

Democrats last week sent Sessions a letter asking him not to assert executive privilege over his conversations with Trump. When Sessions appeared before Senate Intelligence Committee in June, Sessions said he was not prepared to discuss such private conversations in order to give the president an opportunity to assert executive privilege.

On Wednesday, Sessions said he considered the Democrats' request "very respectfully … but I will not be able to discuss the content of my conversations."

The president is entitled to have "confidential" discussions with Cabinet secretaries, Sessions told Senate Judiciary.

In a back and forth with Ranking Member Dianne Feinstein, D-Calif., Sessions declined to answer questions on the firing of former FBI Director James Comey and the presidential pardon of Sheriff Joe Arpaio.

Feinstein first asked Sessions if Trump ever talked with him of "lifting the cloud of the Russia investigation."

"I do not confirm or deny the existence of any communication with the president that I consider to be confidential," Sessions responded.

Feinstein then asked if Trump ever discussed the pardon of Arpaio with him, to which Sessions responded: "I cannot comment on the private conversations I've had with the president."

When asked about the process that led to the Arpaio pardon, Sessions replied: "I don't know that I remember or I know it precisely," and told Feinstein he would get her something in writing on it.

In June, sources told ABC News following Sessions' appearance before the Senate Intelligence Committee that the decision to invoke executive privilege to block Sessions is "in its infancy" and could take months to decide.
