WASHINGTON (AP) - Refusing to be brushed off by Democratic opposition in the Senate, President Bush plans to nominate for a second time 20 people who did not receive up or down votes on their nominations for federal judgeships.

The Democrats' ability to stall certain White House picks for the federal bench was one of the most contentious issues of Bush's first term. During the past two years, despite the GOP majority in the Senate, Democrats used filibusters to prevent final votes from occurring on 10 of 34 of Bush's nominees to federal appeals courts.

"The president nominated highly qualified individuals to the federal courts during his first term, but the Senate failed to vote on many nominations," White House press secretary Scott McClellan said in a statement the White House issued Thursday. "Unfortunately, this only exacerbates the issue of judicial vacancies, compounds the backlog of cases and delays timely justice for the American people."

Senate Majority Leader Bill Frist called for quick action and issued a statement that pressured Sen. Arlen Specter, R-Pa., to support the president's nominees. Specter, a moderate Republican, recently won the backing of Senate Judiciary Committee Republicans to be their new chairman despite his statement that judges who oppose abortion would have a difficult time gaining Senate confirmation, given the opposition from Democrats.

"The president has decided to re-nominate many highly qualified and capable individuals to serve as federal judges," Frist said. "I look forward to working with Sen. Specter, other Judiciary Committee members and my colleagues to ensure quick action and up and down votes on these judicial nominees."
