Senators will start reading the FBI's investigation summaries on Brett Kavanaugh at 8 a.m. ET Thursday, Senate sources said.

Senate Judiciary Chairman Chuck Grassley will read the summaries first, followed by Sen. Dianne Feinstein, the top Democrat on the committee.

Sources said the Senate may physically receive the investigation summaries Wednesday night, but the reading starts Thursday morning.

The Senate will remain in session Wednesday. Majority Leader Mitch McConnell could still file a cloture vote on Kavanaugh’s nomination if the report arrives to Capitol Hill Wednesday night, aides said.
