NEW: After saying they couldn't accept quid pro quo, House Republicans say it no longer matters if tied $400 million in military aid for Ukraine to Kyiv agreeing to investigate Dem rival .
"Republicans now say proof that Trump conditioned military aid to Ukraine to an investigation of Biden...would not shake their opposition to impeachment."
Look, Trump could shoot Ukraine on Fifth Avenue, and it would not budge his support. Not an inch. I know the pro-Trump mindset. And the anti-anti-Trump mindset, too (closely related). Don't nothin' matter. Trust me. The goalposts will always move.
