GOP reps refer Michael Cohen to DOJ for alleged perjury during hearing, page-7

The odd thing about Trump sycophants bloviating about Cohen having previously lied to Congress (which is why he's going to prison)?
He did so to protect Trump.

Now that the details and timeline of the Moscow Tower discussions are out there, the same lie could put little Don Jnr in the cell next door.

Felix Sater knows all the grubby secrets behind this deal.
He's slated to appear before Congress on March 14th.

Won't that be fun.

Trump Jr. told Congress that he “wasn’t involved” in the Cohen-led efforts to build a tower in Moscow, knew “very little” about it, and was only “peripherally aware of it” before news coverage of the matter in 2017.

In short, he minimized his role and pleaded ignorance about the whole thing.

Lying to Congress is a crime. In fact, it’s one Cohen pleaded guilty to in November in connection with his own testimony about Trump Tower Moscow.
  

During that September 2017 testimony, Cohen said that discussions within the Trump Organization about Trump Tower Moscow ended in January 2016. But in November, he pleaded guilty to lying about that, and said discussions about the project actually continued until June 2016. Trump’s new personal lawyer, Rudy Giuliani, has recently suggested they may have continued all the way until October or November 2016.
