A bipartisan duo is calling for renewed U.S. support for Ukraine and taking shots at the Biden and Trump administrations’ handling of the war with Russia amid American efforts to broker a peace deal.

Sens. Mitch McConnell (R-KY) and Jeanne Shaheen (D-NH) urged President Donald Trump in a Washington Post op-ed published Monday not to fall victim to believing Ukraine can’t win and that former President Joe Biden’s “excessive caution” in sending long-range weapons and fighter jets delayed crucial military assistance that could’ve ended the prolonged conflict long ago.
