'Everybody on the left has been walking around town chanting, "watch for the Russian connection, watch for the Russian connection, look for the collusion",' Gingrich said. He said Mueller was a "superb choice" and declared that "his reputation is impeccable for honesty and integrity".
However, Gingrich himself has in the past voted to impeach a president over such charges.
Trump on Friday evening by sharing a tweet touting the conservative host's monologue and the appearance by Gingrich blasting the special counsel. I don't think they're going to get the president, but they're going to get somebody, and they're going to get him for something.
On Thursday, Trump was tweeting his disdain for a new Washington Post report that special counsel Robert Mueller and his team are weighing whether to investigate him for obstruction of justice.
"I, frankly, began to switch the minute Comey, in his remarkable public statement, says, I deliberately leaked to a college professor to leak to The New York Times for the objective of getting a special counsel", Gingrich said.
But Rep. Adam Schiff (D-Calif.) blamed Gingrich's about-face on opportunistic politics.More news: Number of people assumed dead in London tower block blaze to rise

He said Trump was "infuriated" by "this Russia baloney", apparently referring to the ongoing investigation into Russian interference in the 2016 election.
"What's happening here is the president wants to take down Bob Mueller", Schiff added on ABC's "This Week". And the question is why? "One of them is a person who defended the Clinton Foundation".
The former Speaker went on to refer to then-Deputy Attorney General James Comey appointing U.S. Attorney Patrick Fitzgerald to investigate the unauthorized disclosure of the identity of a Central Intelligence Agency employee. "The American people have the right to expect that the rule of law will prevail, that no one is above the law", Gingrich said on the House floor the same year. "And is very pugnacious".
Gingrich said he thinks Trump at this point is "furious". He was flawless, if perfection meant an independent counsel who would squander tens of millions of dollars, prosecute irrelevant defendants, and instigate a wholly unrelated probe of Clinton's sex life, all in order to bring down the Democratic president. "He's been a fighter his whole life".
"98 percent of [media coverage] was positive", Goldberg told former House Speaker Newt Gingrich on Tuesday.
