Another Republican Rep. Urges Support For Ukraine During Peace Talks: 'Can't Be American First And Pro-Russia'

"I think everybody understands is that you can't have, you can't be America first and pro-Russia, because Russia is a self-declared adversary of the United States," he added. "It's fielding new, advanced nuclear weapons that are specifically targeting the United States, it's constantly attacking the United States with offensive cyber, it continuously identifies both NATO and the west, the United States, as its adversary."

The negotiations follow reports about the plans, whose first version would have de facto recognized some regions occupied by Russia, limit the size of the Ukrainian military and have Kyiv agree to never join NATO.

Ukraine has amended the plan and removed some of Russia's demand, officials told The Guardian last week. European leaders said that chances of a deal being reached quickly are slim, and Ukrainian President Volodymyr Zelensky could travel to the White House this week to discuss the plan further.

The initial proposal was also criticized by Republican Rep. Don Bacon, who said he considered resigning after learning the content of the plan. Bacon has called the proposal as the "Witkoff Ukrainian surrender plan," in reference to special envoy Steve Witkoff. He said he will end his term because he has a "commitment to our constituents to fulfill" his term, but will still retire at the end of it, in 2027, as announced.

President Donald Trump said there is a "good chance" for a peace deal between the countries but there is still work to be done. Trump's special envoy Steve Witkoff is set to travel to Russia on Tuesday to meet with Putin following "very productive" talks between Washington D.C. and Kyiv on Sunday.

Zelensky, however, said there are some "tough issues" that need to be worked out. Secretary of State Marco Rubio also said that "so much work remains" but "today was again a very productive and useful session where I think additional progress was made."
