McConnell, noting that it took almost two years for Mueller to conduct his investigation, said: "It's not unreasonable to give the special counsel and the Justice Department just a little time to complete their review in a professional and responsible manner".
Paul Manafort, a former campaign manager of Mr Trump, and Michael Flynn, whom Mr Trump appointed as a national security adviser shortly after assuming office in January 2016, were amongst the top associates of the president arrested on Mr Mueller's findings.
On the other end of Pennsylvania Avenue, his team hammered the probe for two years as illegitimate and based on a Democratic hope that his 2016 campaign conspired with the Russian government to hand him the general election win over Democratic nominee Hillary Clinton. Now the president said he wants some investigations of his own. But asked on Monday if Mueller had acted honourably, Trump said: "Yes".
They said that Congress should be allowed its fair shake at reviewing any "evidence regarding obstruction of justice" as well as the "full body of facts and evidence" related to Russia's online election-related disinformation campaigns.
It was inevitable that in the wake of Attorney General William P. Barr's letter summarizing the determinations made by special counsel Robert S. Mueller III, President Trump would take a victory lap. In a classic case of Washington's ever-changing landscape in the Trump era, Democrats are questioning Barr and even Mueller, while White House officials have begun praising the latter's work.
There's still more action to come from the Justice Department as part of its Russian Federation investigation, but the White House and supporters appear to feel a page has turned in their favor.
Updated 1:13 p.m. | At the White House, special counsel Robert S. Mueller's Russian Federation election meddling investigation has quickly morphed from a "hoax" and a "witch hunt" into the "gold standard".
And the White House's deputy communications director, Adam Kennedy, told NPR on Monday that Schiff and others "were not just completely wrong, they were misleading the public about what the president had done and they deserve to be held accountable for that".
Senator Lindsey Graham, the Republican Senate Judiciary Committee chairman and a Trump ally, told reporters he would ask for an investigation.
Then Democrats will have to deal with Trump until January 2025. Still, he said the investigation was legitimate and had to happen in order to answer questions about Russian interference in the 2016 election.
"Lindsey, let's hope he is not watching right now, and let's hope none of your Republican voters in SC know that you were actually the one who sat and watched Donald Trump trash the memory of an American war hero for weeks", Scarborough said.
But McConnell, noting that it took almost two years for Mueller to conduct his investigation, said, "It's not unreasonable to give the special counsel and the Justice Department just a little time to complete their review in a professional and responsible manner".
Trump also said he had not thought about pardoning anyone convicted or who pleaded guilty in the Mueller probe.
