Mark Senate Judiciary ranking member Jeff Sessions down for Monday in the guessing game over when President Obama will name his Supreme Court nominee.

The Alabama Republican said he doesn't know who Obama will name and hasn't gotten a timeline from the White House, but he speculated the name will come Monday.

"We think -- you know, last time it was on a Monday and so if they follow that pattern, I guess they would do it this Monday," Sessions said. "That's kind of some of the talk."

Why then? "I don't know, really, but I think they were happy on the way it rolled out last time," he said.

While Judiciary Committee Republicans including Sens. Orrin Hatch of Utah, Jon Kyl of Arizona and John Cornyn of Texas spoke in recent days with Obama, Sessions said he hasn't discussed the pick with the president since an April 21 meeting with other key senators. But Sessions said that may be because the White House is familiar with his views on judicial restraint, which he has not been shy about expressing.
