June 4 (UPI) -- Ukrainian officials were set to update U.S. senators on Wednesday on the war and discuss arms purchases and efforts to pressure Russia to negotiate a peace deal, including a tough new bipartisan sanctions bill due to come to the floor of the upper chamber next week.

The delegation, which included Deputy Prime Minister and Economy Minister Yuliia Svyrydenko, Deputy Defense Minister Serhii Boyev and Presidential Office head Andriy Yermak, arrived Tuesday, a day after a second round of Ukraine-Russia peace talks in Turkey broke up without a breakthrough.

Yermak said in a social media post that the delegation was bringing a "comprehensive agenda" of issues that were important to Ukraine to actively promote to members of both parties and President Donald Trump's team.

"We plan to talk about defense support and the situation on the battlefield, strengthening sanctions against Russia, including Senator [Lindsey] Graham's bill. We will also discuss the Agreement on the Establishment of the Reconstruction Investment Fund, which we signed earlier," wrote Yermak.
