The president believes it's time for special counsel Robert Mueller, who was supposed to be investigating Democrat claims of Trump campaign collusion with Russia, either to put up or shut up.
Trump's personal lawyer, former New York Mayor Rudy Giuliani, was all over the networks and social media over the weekend and Monday with the message.
Jonathan Swan at Axios reported Giuliani told him Trump is fed up with Robert Mueller and wants him to "put up or shut up."
Swan quotes Giuliani saying: "Why don't you write a report and show us what you have, because they don't have a g----mn thing. It's like a guy player poker. He's bluffing and he's only got a pair of twos."
Giuliani explained Trump's view is "enough is enough."
The Axois column reported Trump recently tweeted twice about Mueller "in terms that were sharper, and with a more personal edge, than the president's usual rants about the 'witch hunt.'"
He said the president doesn't have plans to fire Mueller but believes it "should get this over now."
Mueller's probe has gone on for a year and a half and so far has filed mostly "process" charges campaign workers unrelated any Trump campaign relationship with Russia.
Giuliani also addressed audio recordings made by former Trump lawyer Michael Cohen explaining only one has Trump on it, and that was revealed last week.
CNBC reported Giuliani also insisted "collusion is not a crime," even though the president has said there was no collusion.
"I have been sitting here looking in the federal code trying to find collusion as a crime," Giuliani said in an interview on Fox News Channel's "Fox & Friends." "Collusion is not a crime."
He later told CNN: "The hacking is the crime. The president didn't hack."
Then he went back to Twitter to accuse the media of "nitpicking."
"You can investigate an innocent person forever and forever and find nothing. When do we say enough is enough. No collusion, no obstruction. President Trump did nothing wrong," he wrote.
Giuliani also said Mueller has "conflicts of interest."
In a tweet, Trump earlier referred to a "very nasty & contentious business relationship" he once had with Mueller, and although Giuliani didn't elaborate, he said Mueller needs to "stand up and be a man."
"He has the conflict, not the president," Giuliani said.
CNBCÂ noted Mueller in 2011 ended his membership at Trump National Golf Club in Virginia after a fee dispute.
Fox News reported liberal icon Alan Dershowitz speculated that Mueller hopes the charges he filed against Paul Manafort will force the onetime Trump campaign manager to reveal something incriminating about the president.
Manafort was charged with conspiracy and other offenses related to the millions of dollars he allegedly made working for the Ukrainian government many years before he worked for the Trump campaign.
On Fox News, Dershowitz said if there's a conviction, it would give Mueller an opportunity to question Manafort about the president's actions.
Dershowitz said to pay attention to whether the prosecution hints at Manafort's relationship with Trump.
"The judge is not sympathetic to this prosecution," he said. "I suspect that we'll see that in some of his rulings."
Fox News reported: "Similarly, Dershowitz said Trump's former attorney Michael Cohen is also 'in a squeeze' and may have to provide evidence against Trump for a 'better deal.' He said witnesses like that sometimes end up 'composing' evidence in a bid for reduced charges or a lesser sentence."
