President Donald Trump blasted The Washington Post Monday night, calling a story about the administration ending a CIA program training Syrian rebels "fabricated," and continued his campaign of abuse aimed at Attorney General Jeff Sessions.

"The Amazon Washington Post fabricated the facts on my ending massive, dangerous, and wasteful payments to Syrian rebels fighting Assad," Trump tweeted late Monday night. "So many stories about me in the @washingtonpost are Fake News."

Trump appeared to be referring to the Post's report last week about a covert program begun by the Obama administration in 2013 that the current administration has decided to end. The Post story said the program's effectiveness has been questioned even by its supporters, but suggested Trump was acting in an effort to improve relations with Russia.

At the time, officials at the White House did not challenge the Post's report, instead saying that the decision was made to shutter the program nearly a month ago, before Trump met with Russian President Vladimir Putin in Germany at the G-20 summit.

The U.S. government has not previously confirmed the program's existence, although Special Operations Commander Tony Thomas appeared to do so at the Aspen Security Forum last week, before trying to walk it back.

In his tweets Monday night, Trump went on to repeat accusations that Amazon founder Jeff Bezos, who bought the Post in 2013, is using the newspaper to try to avoid taxes.

"Is Fake News Washington Post being used as a lobbyist weapon against Congress to keep Politicians from looking into Amazon no-tax monopoly?" he wrote.

And in a series of tweets Monday morning, he continued to attack Sessions amid reports he is discussing firing him as attorney general.

"Ukrainian efforts to sabotage Trump campaign - 'quietly working to boost Clinton.' So where is the investigation A.G." Trump tweeted, tagging Fox News host Sean Hannity, who often alleges on his nightly show that the news media is ignoring what he calls scandals and crimes committed by former Secretary of State Hillary Clinton.

"Attorney General Jeff Sessions has taken a VERY weak position on Hillary Clinton crimes (where are E-mails & DNC server) & Intel leakers!" Trump continued. "Problem is that the acting head of the FBI & the person in charge of the Hillary investigation, Andrew McCabe, got $700,000 from H for wife!"

Trump has made a habit of criticizing Sessions on a nearly daily basis since last week, when he told The New York Times in an interview that he regretted appointing Sessions.

And on Monday, he called Sessions "beleaguered" for failing to "look into Crooked Hillarys crimes & Russia relations."

Firing Sessions, or forcing him to resign, is seen as an attempt to remove Special Counsel Robert Mueller, who was appointed by Deputy Attorney General Rod Rosenstein to oversee the probe into Russian interference and possible collusion with Trump's campaign after Sessions recused himself in March from any investigations relating to the 2016 election.

Trump has raged against the investigation, calling it a "hoax" and a "witch hunt," and said Democrats were using the probe to excuse their losses at the ballot box.

On Tuesday, he took another swipe at the investigation's latest direction, which has moved to investigate his son-in-law and White House senior adviser Jared Kushner's business ties and meetings with Russian officials during the campaign.

Kushner met with congressional investigators on Monday, after which he said in a rare public statement that he "did not collude, nor know of anyone else in the campaign who colluded, with any foreign government."
