Special counsel Robert Mueller’s team is eyeballing derogatory tweets and negative statements made by President Trump about Attorney General Jeff Sessions and fired FBI chief James Comey as part of his probe into Russian election meddling, a new report said Thursday.

Some of the comments came as Trump was privately pressuring the pair, who are both key witnesses in Mueller’s probe, to quit or put the kibosh on the probe, which is also looking at possible collusion with Trump’s campaign, the New York Times reported.

Mueller is investigating whether the tweets and statements — including those from spokeswoman Sarah Huckabee Sanders — constitute attempts to obstruct the probe by intimidating witnesses.

The special counsel is also scrutinizing other actions taken by the president, including his private conversations with Comey, Sessions and other administration officials about the Russia inquiry, misleading statements from the White House, vituperative public attacks on key figures in the case and whether he offered pardons to potential witnesses.

Mueller’s team told Trump’s lawyers they were probing the tweets under a wide-ranging obstruction-of-justice law that was strengthened after the Enron scandal, three sources told the Times.

The president’s lawyer and loquacious TV defender Rudy Giuliani scoffed at the thought that tweets could amount to obstruction.

“If you’re going to obstruct justice, you do it quietly and secretly, not in public,” Giuliani told the paper.

The commander-in-chief has attacked and insulted Sessions and Comey repeatedly on Twitter, in person and at rallies and in other public comments.

He was furious with Sessions after the AG recused himself from the Russia probe, and called Comey “a real nut job” as he met with a pair of Russian officials in the White House days after firing him.

Canning the top G-man, he told the Russians, took pressure off him in the Russia investigation.

Investigators want to question Trump about the tweets he wrote about Sessions and Comey and why he continued to publicly denigrate Comey and ex-Deputy FBI Director Andrew McCabe, another witness against the president.

After Trump pressured Sessions to resign last July, Trump launched a blistering series of public attacks on the former Cotton State senator.

Mueller’s deputies also told Trump’s legal team that they wanted to question the president about similar statements at the time by Sanders, according to the report.

“The Department of Justice has to look into any allegations of whether or not something is illegal or not,” Sanders said at a press briefing last September.

“That’s not up to me to decide. What I’ve said and what I’m talking about are facts. James Comey — leaking of information, questionable statements under oath, politicizing an investigation — those are real reasons for why he was fired.”
