Before Trump's inauguration, the U.S. ruling and opposition parties are fiercely competing for leadership

Democrats and Republicans in the U.S. are vying for judicial leadership, including the right to nominate federal judges, ahead of President-elect Donald Trump's inauguration.

The Washington Post reported that the three federal judges nominated in the Democratic administration originally said they would retire if the Senate confirmed their successor, but changed their positions after Trump's presidential victory.

A federal judge cannot be replaced unless he is impeached or has health problems because he is a life-long position, which has disrupted Republican plans to have Trump name a Republican-leaning judge to replace him once he takes office.

In the meantime, President Biden vetoed the so-called "judge law," which would establish federal judges across the United States, after Trump was expected to nominate 25 of the 66 new judges.

Biden has appointed 235 judges in his tenure, one more than during Trump's first term, as Democrats have accelerated to confirm as many judges as possible after his presidential defeat.
