President Trump slammed Sen. "I believe when the history of this era is written, the heroes will be the free press and the independent judiciary who have upheld the rule of law against threats by the Trump administration".
A Democratic senator appeared on CNN to accuse President Donald Trump of colluding with Russian Federation during the campaign and obstructing justice afterward - and the president lashed out minutes later.
In fact, Blumenthal never served in Vietnam, but had obtained at least five military deferments from 1965 to 1970 and took repeated steps that enabled him to avoid going to war, according to records obtained by the Times.
Mr Trump had called for an investigation of Mr Blumenthal for the Vietnam service issue earlier this year as well, posting on Twitter that "When caught, he cried like a baby and begged for forgiveness. and now he is judge & jury".
"With broad mandate Special Counsel must pursue all financial dealings - past and present - involving Russians and Trump campaign", Blumenthal wrote on August 5. "No one is above the law", he tweeted. He said Mueller's investigation must be pursued. "I take full responsibility, but I will not allow anyone to take a few misplaced words and impugn my record of military service", said Blumenthal in CT newspaper The Day at the time.

Is tweeting a better idea than bombing North Korea? He said Japan and the United States would take steps towards concrete action but did not give details.
Trump's description of the senator as a "Vietnam con artist" was seemingly a reference to speeches Blumenthal made implying he had served in Vietnam. Now he judges collusion?'
"The Trump base is far bigger and stronger than ever before (despite some phony Fake News polling)", the president wrote, over a series of three tweets.
Blumenthal and Trump share a dishonorable history with Vietnam service.
In February, after Blumenthal pledged to block Trump's Supreme Court nominee Neil Gorsuch, Trump criticized CNN anchor Chris Cuomo for not asking Blumenthal about his Vietnam record. The senator admitted in 2010 to misrepresenting his military service after saying he had been "in" Vietnam.
A representative from Blumenthal's office said the tweets were standing as the Senator's response.
