Washington (CNN) CNN's report that Michael Cohen claims then-candidate Donald Trump had advanced knowledge of the June 2016 Trump Tower meeting between Donald Trump Jr., Jared Kushner, Paul Manafort and Russian lawyer Natalia Veselnitskaya with supposed "dirt" on Hillary Clinton has created a fresh wave of scrutiny about the now-infamous gathering.

Cohen's reported claims, if true, would be at odds with repeated denials that Trump was not told of the meeting beforehand, and raise the prospect that Trump Jr. lied to Congress about the meeting.

Three congressional committees have investigated the circumstances surrounding the Trump Tower meeting, and two of those -- the House Intelligence Committee and the Senate Judiciary Committee -- have either issued reports or released transcripts of their probes into the meeting.

The documents and testimony, as well as t he emails exchanged between Trump Jr. and British music publicist Rob Goldstone, provide a picture of what we know so far about the days surrounding the Trump Tower meeting -- and how Cohen's claims might fit into or upend that narrative.

Here's a day-by-day look at how the Trump Tower meeting happened:

MR. TRUMP JR.: Again, the majority was really split up between -- really started off as Russian adoption, which was sort of the, you know, what I perceive to be sort of the feelgood segue to probably lobbying for something as it related to that Act. So, you know, I'd say we spent less than, you know, 5 minutes of the 20 minutes, again, speaking through a translator about the quote/unquote "dirt", and the rest was a quick segue, bait-and-switch, whatever you want to call it, to speak about Russian adoption and the Magnitsky Act.

MR. SCHIFF: And do you recall Don Jr. asking whether Veselnitskaya had anything on Hillary Clinton?
