WASHINGTON —The Senate Foreign Relations Committee plans to hold an open hearing in January that will examine possible meddling by Russia in last month’s presidential election.

An aide to Sen. Bob Corker of Tennessee says he and Ben Cardin of Maryland received a classified briefing on cyber threats prior to the Nov. 8.

Corker is the committee’s Republican chairman and Cardin is the top Democrat on the panel.

The aide was not authorized to speak publicly and requested anonymity.

Corker said on MSNBC Tuesday that the Director of National Intelligence, the CIA and the FBI differ over whether Russia interfered to help Donald Trump win the White House. He says, “I know that’s frustrating to people.”
