The lawyer who had long worked for Donald Trump as his self-described "fixer" has admitted to lying to US Congress over the Russia investigation.
The question now is what this means for the US President himself — and specifically, how Michael Cohen's new account of events squares with what Mr Trump had told special counsel Robert Mueller.
Let's take a closer look at this latest development. Cohen has given a new version of events when it comes to Mr Trump's business dealings in Russia
Here's what the court documents say:
* He told Congress in a written statement in 2017 that a Trump Tower project in Moscow had ceased by January 2016, but now he says they didn't stop until June 2016 (after Mr Trump became the Republican presidential nominee)
* In January 2016, Cohen spoke with an assistant to Russian President Vladimir Putin's spokesperson about moving the project forward
* In May 2016, Cohen talked to a Trump Organisation official about making a trip to Russia in relation to the project
* Cohen discussed the real estate project with Mr Trump on multiple occasions and with unidentified members of the President's family
Cohen says the reason he lied was to be consistent with Mr Trump's "political messaging".
However, nothing said in court or in associated court filings addressed whether Mr Trump or his aides had directed Cohen to mislead Congress.
There is also no clear link in the court filings between Cohen's lies and Mr Mueller's central question of whether the Trump campaign colluded with Russia.
What's relevant is that Mr Trump had insisted repeatedly during the 2016 campaign that he had no business dealings in Russia
