Mr Trump tweeted: "Collusion is not a crime, but that doesn't matter because there was No Collusion (except by Crooked Hillary and the Democrats)!"
President Trump speaks about the economy during a statement on the South Lawn of the White House on Friday.
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'".
"Collusion is basically a partnership in crime, which is conspiracy", said Randall Eliason, a former federal prosecutor and a law professor at George Washington University.
The former mayor of New York City said it would take more analysis to say whether Judge Kavanaugh is accurate.

Millions of Americans watched the first solar eclipse visible from the US since 1979 last August. It will be at opposition, which means that it's at the opposite side of the Sun to the Earth.
MSNBC's Nicolle Wallace put the freaky spectacle of Rudy Giuliani's latest media blitz in context Monday, showing how convoluted and twisted President Donald Trump's defenses of his own actions with regard to Russian interference in the 2016 election have become.
"I can't keep with Rudy Giuliani's theories of defense", Durbin said.
Fordham University law professor Jed Shurgerman concurred, writing in Slate last week that "while "collusion" might not be a crime under any federal statute, any collusive conduct by the Trump campaign could be prosecuted as a 'conspiracy against the United States'".
Special Counsel Robert Mueller's team of investigators into the Trump campaign has indicted several Russian nationals and five American Trump associates on charges including Manafort, whose trial regarding allegations that he laundered $30 million on behalf of pro-Russia Ukrainian politicians begins Tuesday.
Giuliani also said Mueller has "conflicts of interest".
Should Manafort be convicted, the investigation by Mr Mueller could gain some momentum.
