While most Republicans have avoided commenting on the latest allegations against President Trump and his call with the Ukrainian president earlier this summer, two prominent Senate Republicans spoke out over the weekend, asking the White House to release information about the phone call.

Sen. Lindsey Graham (R-SC), who is considered to be one of Trump’s closest allies in Congress, told the New York Times that he hopes the White House can find an “appropriate way” to share the contents of the phone call, stopping short of criticizing any of Trump’s actions.

“I’m hoping the President can share, in an appropriate way, information to deal with the drama around the phone call,” Graham said. “I think it would be good for the country if we could deal with it.”

Sen. Mitt Romney (R-UT) had stronger words of criticism for Trump and the White House, tweeting on Sunday that it was “critical for the facts to come out” and saying if reports about Trump pressuring Ukraine to help with his reelection were true it would be “troubling in the extreme.”

While Republicans remain tight-lipped, the new developments surrounding the whistleblower complaint have pushed more Democrats to elevate calls for impeachment. House Speaker Nancy Pelosi (D-CA) has avoided publicly embracing the term, but wrote in a letter to colleagues on Sunday that if the White House continues to hide the contents of the complaint it would lead to a “whole new stage of investigation.”
