U.S. Senate Majority Leader Mitch McConnell on Tuesday sought to slam the door on further investigations of President Donald Trump by declaring “case closed” after a two-year probe of Russia’s meddling in the 2016 elections, even as House Democrats’ war with the White House intensified.

McConnell, the top Republican in the U.S. Congress, delivered a stinging rebuke of Democrats seeking additional information on special counsel Robert Mueller ‘s report that found no evidence Trump’s 2016 campaign colluded with Russia.

“The special counsel’s finding is clear. Case closed,” McConnell declared.
