Trump ex-lawyer admits lying to Congress

Been on the news all day!

How do we know if he is lying again?

SInce he admitted to lying and if he gets jail time etc my question is this...a lie is a lie correct? What happens to others that have lied under oath to the Senate or Congress???? I.e. kavanaugh accusers, Diane Feinstein about her driver who was a spy and admitting to not releasing the data on Kavanaughs accuser...if a lie is a lie under oath hold all of them accountable...Don't pick and choose who gets jail time or not. Either all in or all out.
