Cohen initially lied and said the Trump Tower Moscow talks ended in January 2016, but he admitted last month those conversations extended through June 2016 when he pleaded guilty to lying to Congress about the project.
As Trump's longtime lawyer and "fixer", Cohen had connections to a number of the key questions surrounding the president, the Mueller probe and now the Democratic congressional investigations.
Former U.S. federal prosecutor Roland Riopelle called it "a very frightening development" for Trump.
"Mr. Cohen has expressed an interest in telling his personal story in open session, and we welcome his testimony before the Committee on Oversight and Reform".
Special Counsel Robert Mueller for many months has been investigating Russia's interference in the 2016 us presidential election, possible collusion between the Kremlin and the Trump campaign and potential obstruction of justice.
Trump's attorney Rudy Giuliani described Cohen to Fox News as "a thoroughly discredited liar", and said he could not imagine why Cummings would want to hear from Cohen.
The women have claimed they had affairs with Trump after the real estate mogul married his third wife, Melania.
"Recently, the President tweeted a statement calling me 'weak, ' and he was correct, but for a much different reason than he was implying", Cohen said at the time. Add Donald Trump as an interest to stay up to date on the latest Donald Trump news, video, and analysis from ABC News.
During his sentencing, Cohen said his "blind loyalty to this man [Trump] that led me to choose a path of darkness over light".
Democrats won back the House past year promising to hold Trump and his administration to account and have begun laying the groundwork for a long run of investigations targeting his administrator's policies and ethics lapses, Trump's businesses and his campaign's interactions with Russian Federation.
Trump and his backers also tried to downplay the payments, calling them a "simple private transaction", even though they could run foul of campaign finance laws. Cohen's appearance in public, before national television cameras, will begin to fulfill that promise, but is likely to only be the first of a string of public testimony that could prove damaging to the president. In court filings, prosecutors have not named Trump, referring to a "candidate for federal office" and "Individual-1".
A judge also ordered Cohen to forfeit $692,000 and pay restitution of almost $1.9 million. "The Committee will announce additional information in the coming weeks".
The president has assailed the various investigations, while Russian Federation has denied trying to interfere in the 2016 election for the purposes of sowing discord and improving Trump's prospects.
Given Cohen's prolonged time spent in proximity to Trump, his family and the Trump Organization, some insiders consider his cooperation with authorities to be one of most serious potential legal threats to confront the president. But the voters weren't fully aware of its existence.
Committee chairman Rep. Elijah E. Cummings (D-Md.) in a statement on Thursday thanked Cohen for agreeing to testify amid special counsel Robert Mueller's ongoing investigation.
The president has denied the affairs but has deployed shifting explanations about when he learned about the payments to the women.
