President Obama will announce his nominee to fill a vacancy on the Supreme Court in the White House Rose Garden at 11 a.m., he said in an email to supporters Wednesday.

While Senate Republicans have said they will not consider any jurist the president nominates for the nation’s highest court, Obama sent out an email to supporters declaring he was prepared to do so. Late last week Obama had narrowed the list of potential nominees to three federal appeals judges: Sri Srinivasan, Merrick Garland and Paul Watford.

Both Srinivasan and Garland sit on the U.S. Court of Appeals for the District of Columbia Circuit, while Watford sits on the Ninth Circuit Court of Appeals.
