And to the argument that the Senate won't convict, that doesn't matter. The PROCESS of impeachment will affirm that the rule of law still matters, and it can focus the national spotlight on the sheer magnitude of Trump/Pence's corruption.
#Impeachment hearings would tell the world American democracy is still alive and that kleptocracy and creeping fascism haven't completely destroyed the rule of law. House Dems refusing to do it is a failure, and will cost us dearly. No sugarcoating it.
