Because newly elected President Zelensky (voted in by the anti corruption/anti Putin movement in Ukraine) needed some reminding?
And to refresh Zelensky's memory, best to freeze nearly $400 million in US military aid? Only to release that aid 2 days after Inspector General's Whistleblower letter is sent to Congress?
And by the way, to ask for a favor, .... that coincidentally involved looking into VP Biden?
And to bring up CrowdStrike -- the myth fed by ... wait for it ... Putin, that it was Ukraine (not Russia) who hacked the DNC in 2016?
Keep living in Dreamland, Eli.
