A $1 million donor to Trump’s inauguration committee who later became the EU ambassador is now on record saying he told a Ukrainian official that the country wouldn't get military aid unless they caved to President Trump's demands.

“If it were today I don’t think there’s any question — it would not lead to a removal," Majority Leader Mitch McConnell said today.
