Leaders in the Democratic party may not be able to block President Donald Trump's White House Cabinet appointees from being confirmed by a Republican-majority Senate, but they can certainly get under his skin. Trump was tweeting his frustrations over ongoing delays for two Cabinet positions Friday, including the secretaries for the Department of Agriculture and Department of Labor.

"It is so pathetic the Dems have still not approved my full Cabinet," Trump tweeted Friday morning, just hours after a late-night tweetstorm blasting the Democratic party following Attorney General Jeff Sessions' recusal from the Justice Department's investigation into the president's reported ties to Russia.

Despite Trump's suggestion the Democratic party is delaying Cabinet confirmations, his two remaining nominations have had extenuating circumstances that have curbed the Senate's ability to schedule hearings.

Alexander Acosta, Trump's pick to lead the Department of Labor, was only nominated in February following the withdrawal of the president’s initial choice for secretary, Andrew Puzder.

Several controversies clouded Puzder’s nomination, including recent reports the businessman owed at least $1,000,000 to UBS, a controversial banking and financial services group. Democratic leaders celebrated the withdrawal, including Vermont Sen. Bernie Sanders, who said he was "glad" Trump’s pick gave up the nomination.

"The simple truth is that given his relationship to employees at the companies he runs, he was not fit to lead a department responsible for defending workers’ rights," Sanders said in a statement emailed to International Business Times Feb. 15. "We need a secretary of labor who is going to fight to raise the minimum wage to a living wage of $15 an hour and pay equity for women. We don’t need a labor secretary who makes millions while his workers are paid starvation wages."

Meanwhile, Trump's administration reportedly has yet to provide the Senate with necessary paperwork to begin the confirmation process for former Georgia Gov. Sunny Perdue, the nominee for agriculture secretary.

Trump continued to put the spotlight on the embattled Democratic party and leaks coming from within his own administration Thursday, suggesting investigations into his White House's ties to the Russian Kremlin are a "witch hunt."

"The Democrats are overplaying their hand," Trump said on Twitter Thursday night. "They lost the election, and now they have lost their grip on reality. The real story is all of the illegal leaks of classified and other information. It is a total 'witch hunt!'"
