President Donald Trump, at the 200-day mark of his presidency, remains behind previous presidents in nominations for staff positions in his administration as well as confirmations of those nominations.

The Senate confirmed more than five dozen nominations last week, bringing the Trump administration's total to 277 people, with 124 confirmations, according to CNN's tracker.

Roughly 4,000 positions must be filled in a new administration, and more than 1,200 of those require Senate confirmation. Partnership for Public Service, a nonprofit group, recommends having the most important 300 or 400 confirmed by the time of the August recess, according to CNN.

Trump's rate of 45 percent of nominees confirmed at the 200-day point is behind former Presidents Barack Obama, George W. Bush, and Bill Clinton. At this point, Obama had 72 percent confirmed, Bush had 71 percent and Clinton had 73 percent.

Senate Democrats have been requiring Republicans to take all the procedural steps for the nominations, which drags out the process, according to CNN's tracker.

However, the Trump administration also has been slow in transmitting nominations to the Senate for formal consideration after the nomination has been announced.

Partnership for Public Service said 577 positions in the executive branch are a top priority. Trump has successfully filled about one-fifth of them, CNN reported.

Max Stier, the president of Partnership for Public Service, said that filling positions is necessary for Trump to pursue his agenda more successfully.

"The president must prioritize getting his full team in place. Doing so will strengthen his ability to run the government, achieve his priorities and deal effectively with the inevitable crises that will take place in our complicated and dangerous world," Stier said, according to CNN.

Only seven of the 15 Cabinet agencies have top deputies confirmed, so career civil servants are in acting roles and are handling those operations, according to The Washington Post on Friday.
