Hours after he sacked the acting attorney general for refusing to defend his immigration order, President Trump took to Twitter to hammer Senate Democrats for slow-walking the confirmation process of his nominee to head the Justice Department.

The Senate Judiciary Committee was set to meet Tuesday morning regarding Sen. Jeff Sessions’ nomination to be attorney general. But Sessions' initial hearing was all the way back on Jan. 10, and only a handful of Trump’s Cabinet picks have been voted on, a dozen days into his presidency.

“When will the Democrats give us our Attorney General and rest of Cabinet! They should be ashamed of themselves! No wonder D.C. doesn’t work!” Trump tweeted Tuesday morning.

SESSIONS ONCE GRILLED YATES ON SAYING 'NO' TO PRESIDENT

Trump fired Acting Attorney General Sally Yates on Monday evening after the Obama administration holdover refused to defend Trump’s controversial executive order placing restrictions on immigration. He replaced Yates with Dana Boente, the U.S. attorney for the Eastern District of Virginia; but Boente is only a placeholder until – and if – Sessions is confirmed.

Trump also used his early-morning tweeting to hammer Democrats – namely House Minority Leader Nancy Pelosi and Senate Minority Leader Chuck Schumer – who protested his executive order on Monday.

“Nancy Pelosi and Fake Tears Chuck Schumer held a rally at the steps of The Supreme Court and mic did not work (a mess)-just like Dem party!” he tweeted.

Pelosi's spokesperson shot back at Trump later Tuesday morning.

"The mic briefly didn’t work, but this thin-skinned President clearly heard the voices of the more than 250 Members of Congress and thousands of others who gathered outside the Supreme Court last night," spokesman Drew Hammill said in a statement. "The President’s immoral executive order is clearly unconstitutional – no matter how many times he tweets or how many Administration officials he fires."
