Trump also insisted he and his campaign had not colluded with Moscow in last year's election, and shifted blame on the Justice Department and his Democratic rival Hillary Clinton.
"I never asked Comey to stop investigating Flynn. Just more Fake News covering another Comey lie!" Trump said in a tweet.
But his position was complicated by another Twitter post in which he indicated he had fired Flynn because the national security chief had been untruthful not just to Vice President Mike Pence but to the FBI as well.
"If that is true, Mr. President, why did you wait so long to fire Flynn?" asked Representative Adam Schiff of California, the top Democrat on the House Intelligence Committee.
"Why did you fail to act until his lies were publicly exposed? And why did you pressure Director Comey to 'let this go?'"
White House officials, however, told The New York Times that Trump was only referencing Flynn's guilty plea for lying to the FBI about his conversations with then Russian ambassador Sergey Kislyak over sanctions president Barack Obama slapped on Russia for election meddling.
After he was fired himself in May, Comey testified under oath before a Senate panel that, a day after Flynn's firing, Trump asked him to drop an investigation into the former national security advisor.
A lingering part of the drama has been that after the White House learned through the Justice Department that Flynn lied to the White House about discussing sanctions with the Russian ambassador, Trump still waited 18 days to fire him.
Mueller's focus goes beyond possible collusion with Russia to business dealings and whether Trump himself tried to thwart the investigation.
US media reported that senior FBI counterintelligence official Peter Strzok was removed from the investigation over the summer for sending text messages critical of Trump.
Trump retweeted a post from conservative commentator Paul Sperry about the news that highlighted the fact that Strzok had also worked on the probe into Hillary Clinton's use of a private email server while serving as secretary of state.
Earlier, Trump renewed focus on the Justice Department's handling of the Clinton probe.
"So General Flynn lies to the FBI and his life is destroyed, while Crooked Hillary Clinton, on that now famous FBI holiday 'interrogation' with no swearing in and no recording, lies many times...and nothing happens to her? Rigged system, or just a double standard?" he wrote.
"Many people in our Country are asking what the 'Justice' Department is going to do about the fact that totally Crooked Hillary, AFTER receiving a subpoena from the United States Congress, deleted and 'acid washed' 33,000 Emails? No justice!"
"What has been shown is no collusion. There's been absolutely no collusion. So we're very happy," Trump said.
Comey himself seemed to be addressing the latest developments in an Instagram message: "To paraphrase the Buddha -- Three things cannot be long hidden: the sun; the moon; and the truth."
The explosive new developments in the Russia probe have overshadowed a major legislative win for Trump: the Senate's passage of the most significant US tax overhaul in 31 years.
