• Trump's tweets come the night before the special counsel Robert Mueller is expected to submit several important filings related to the Russia probe.
• Friday is the deadline for Mueller to submit documents outlining former campaign chairman Paul Manafort's "crimes and lies," which include his alleged violations of the plea deal with the special counsel.
• The special counsel is also expected to submit a sentencing recommendation for former Trump attorney Michael Cohen, who pleaded guilty to financial crimes and lying to Congress.

President Donald Trump fired off a series of tweets on topics that ranged from the Russia investigation and border security on Thursday evening, the night before the special counsel Robert Mueller is expected to submit several important filings related to the Russia probe.

Trump fired off two tweets relating to a Fox Business segment with anchor Trish Regan, in which she sought to cast doubt on the FBI's justification for obtaining a FISA warrant to surveil former Trump campaign adviser Carter Page.

Regan referenced the infamous Democratic-funded dossier, which was reportedly used as justification for the FISA warrant, and suggested "the FBI was weaponized in order to take down President Donald Trump."

"Is this really America," Trump tweeted, referring to Regan's comments questioning the FISA warrant's legitimacy. "Witch Hunt!"

In another tweet one minute later, Trump revived his go-to attack on the news media.

Trump went on to mention Arizona, which he claimed was "bracing for a massive surge at a NON-WALLED area."

Trump appeared to be referring to the Customs and Border Patrol's training exercise in Tucson, Arizona, on Thursday, where agents prepared "to deal with the potential of large crowds and assaultive behavior by caravan members, should a situation arise."

Trump also referenced minority leaders Nancy Pelosi and Chuck Schumer, who railroaded Trump's plans for a $5 billion down payment on the controversial wall between the US-Mexico border.

"WE WILL NOT LET THEM THROUGH," Trump tweeted. "Big danger. [Rep. Nancy Pelosi] and [Sen. Chuck Schumer] must approve Boarder Security and the Wall!"

Trump's rapid-fire tweets come the night before Mueller's deadline to submit documents outlining former campaign chairman Paul Manafort's "crimes and lies," which includes the alleged violations he made from his plea deal with the special counsel. Manafort pleaded guilty to one count of conspiracy to obstruct justice and one count of conspiracy against the US in September.

The special counsel is also expected to submit its sentencing recommendation for former Trump attorney Michael Cohen, who pleaded guilty to financial crimes and lying to Congress.

Mueller's recommendation follows a similar one filed for former national security adviser Michael Flynn, who was found to have lied to federal investigators about his contacts with Russian officials.
