The Republican Party on Monday stepped up its fight against any U.S. Supreme Court nominee put forward by President Barack Obama while the president¡¯s allies hit back against a conservative group¡¯s attack on a judge who had been considered for the job.

The Republican Party¡¯s move to create a task force to coordinate advertising and other steps to assail Obama¡¯s nominee to fill the vacancy left by the Feb. 13 death of conservative Justice Antonin Scalia is the latest indication that the political fight could become very nasty.

¡°It¡¯s clear what Republicans are planning to do,¡± White House spokesman Josh Earnest said. ¡°They are planning to tear down the president¡¯s nominee, without regard to who that person is.¡±
