Trump accused Cohen of fabricating stories about his Russian Federation dealings to minimise his sentence on multiple counts of tax evasion, financial fraud and campaign finance violations that he has admitted in federal court in NY.
After railing against Cohen, his close associate for more than a decade, Mr Trump congratulated Roger Stone, a political operative involved in his campaign, for saying that he would refuse to testify to the Russian Federation investigation led by Robert Mueller.
Mueller's team also entered a deal last week with former longtime Trump personal attorney Michael Cohen, after he pleaded guilty to making false statements to Congress regarding his description of the Trump Organization's plans to build a Trump Tower in Moscow.
"You mean he can do all of the awful, unrelated to Trump, things having to do with fraud, big loans, Taxis, etc., and not serve a long prison term?" he said.
Special counsel Robert Mueller recommended that former National Security Adviser Mike Flynn receive a sentence for lying to the Federal Bureau of Investigation that included no prison time, in a court filing Tuesday that called Flynn's cooperation "substantial".
But for the most part, prosecutors will spell out in detail the matters they believe the former Trump campaign chairman misled them about, and their public disclosures could shed new light on where the Russian Federation investigation stands. He also pleaded guilty in the Mueller investigation to one count of lying to Congress last week, and his lawyers say he expects to cooperate further. The man he wants to see in jail is Michael Cohen, who is cooperating with Robert Mueller's investigation after taking a plea deal.
Bloomberg said the tweet about Stone "looks like what any vigilant prosecutor might construe as "witness tampering" - an obstruction of justice.

It is unusual for a president or any senior government official to comment on court proceedings.
In an ABC News interview on Sunday, Stone, a veteran Republican political consultant, denied any impropriety and said he would never give evidence against Trump, with whom he has worked for four decades.
The Republican president has repeatedly attacked Mueller's probe and expressed sympathy for former associates caught in its web, including ex-campaign chairman Paul Manafort, who faces sentencing after convictions of tax and bank fraud charges.
The president then said it's nice to know that some people still have guts. In his court statement, Cohen said that he lied "out of loyalty" to the president.
