Senate Democrats called on Republicans to vote on Merrick Garland's nomination to the Supreme Court by Memorial Day, as GOP lawmakers showed no sign of relenting despite the latest round of courtesy calls.

Senate Majority Leader Mitch McConnell, R-Ky., maintains that the president chosen by voters in November should fill the vacancy on the high court, and there will be no confirmation hearings or a vote. But Senate Minority Leader Harry Reid and his Democratic colleagues are hoping that election-year pressure will eventually wear them down.

"We feel the public is on our side, and this is to their detriment," Reid told reporters Thursday at a news conference in which Democrats pressed for consideration of Garland's nomination.

One Republican in a tough re-election race, Sen. Rob Portman of Ohio, met with Garland Thursday morning and told the judge that he agreed with McConnell on delaying the nomination until after the next president takes office.
