Cohen, in a Manhattan Supreme Court filing, charged Thursday that the Trump Organization reneged on a July 2017 agreement to cover his attorneys' fees and costs in connection with the lawyer's legal representation regarding investigations of President Donald Trump.
The statement went on: "During that time period, he directed his attorney to explore possibilities of a pardon at one point with Trump lawyer Rudy Giuliani as well as other lawyers advising President Trump".
Once Trump's trusted fixer, Cohen has had a bad break-up with the President, over the hush money payment to porn star Stormy Daniels. Mueller is investigating possible co-ordination between Russian Federation and Trump's 2016 presidential campaign. Despite saying he wanted to build a Trump Tower in Russia, Trump never completed a deal.
It says that was around the time Cohen began discussing privately with friends and family that he was considering cooperating with special counsel Robert Mueller and federal prosecutors in NY.
Cohen was sentenced to three years in prison for a variety of crimes, including campaign finance violations. Weisselberg was also among the dozens of people who received a request for documents this week from the House Judiciary Committee, which is investigating alleged abuses of power by the president.
Rep. Jim Jordan, the top Republican on the House Oversight Committee, blasted Michael Cohen as an "admitted liar" on Thursday over new revelations that raised questions about the veracity of last week's testimony to Congress - and challenged committee Chairman Elijah Cummings to back calls for a Justice Department review of the former Trump attorney's statements. But that may not be the full story.
The person was not authorized to discuss the matter publicly and spoke to The Associated Press on condition of anonymity.
Voters believe Cohen over Trump, according to the poll, which found that 50 percent of voters said they believed Cohen while 35 percent said they believed Trump. Cohen did not participate in the conversation.
Congressional investigators are also looking into whether anyone on Trump's legal team tried quietly to reach out to Cohen past year before he turned on the president and as his legal problems mounted.
Cohen's response came within minutes and featured two references to Trump's "lies".
He said these included two lawsuits by Daniels, the NY attorney-general's lawsuit concerning Mr Trump's namesake charity, the Mueller and congressional probes, and his criminal case.
Schiff said that his legislation would address instances when the president initiates a pardon for an individual linked to an investigation in which the president or a family member is a subject, target or witness. Cohen told a House committee last week that he had briefed Trump Jr. approximately 10 times about the plan. Schiff would not comment on the substance of the interview but said it helped "to shed light on a lot of issues that are very core to our investigation". It has emerged as a key line of inquiry for Democrats launching a series of sweeping investigations into Trump's political and personal dealings.
