Sally Yates lied to trump [but not to Congress]

When Sally Yates went hurriedly to the WH [Don McGahn/trump] to tell them Mike Flynn had lied to the VP, and was potentially compromised, she was lying.

Yates was correct: Flynn was horribly compromised, and couldn't be NSAdviser [took a while to fire him though, didn't it], but she also knew that Pence was fully aware of Flynn's compromised position. She was giving trump an 'excuse' [one he didn't want, but couldn't dismiss] to get rid of Flynn.

When trump/pence figured out that Yates knew the VP wasn't lied to [since he was aware of Flynn's connections via Elijah Cummings, they realized how truly DANGEROUS Yates [and others in the IC/DOJ] were to them, so she was fired. First of many.

I bring this up now b/c going forward, we are going to see a lot more of Yates, Comey, maybe even President Obama [since trump foolishly accused Obama of 'spying' on hiim], at various trials and committee hearings.

Imagine President Obama, sworn in and testifying!
