Two Twin Cities suburban House members joined a growing group of moderate Democrats on Monday voicing support for impeachment proceedings against President Donald Trump over allegations that he pressured a foreign leader to dig up dirt on his top Democratic rival.

Reps. Angie Craig and Dean Phillips, both freshman Democrats representing metro area swing districts, cited reports that Trump pressed the Ukrainian government to investigate the son of former Vice President Joe Biden, whom the president has accused of corrupt business practices overseas.

"It is clear that the sitting president of the United States placed his own personal interests above the national security of the United States," said Craig, whose district includes the southern Twin Cities suburbs. "When there is an abuse of power of this magnitude, it is our responsibility to stand up for what is right. This is why I am calling to open impeachment proceedings — immediately, fairly and impartially."

Phillips, representing the western Twin Cities suburbs, said the president's actions, alleged in a whistleblower complaint, would be tantamount to "inviting foreign interference in our democracy … that is corrupt at best, treasonous at worst, and puts our rule of law at risk."

"If the reports are corroborated," Phillips continued, "we must pursue articles of impeachment and report them to the full House of Representatives for immediate consideration."

The moves by Craig and Phillips reflected a shift in recent days among moderate Democrats who have been reluctant to join calls for Trump's impeachment in connection with the Special Counsel investigation of Russian interference in the 2016 election and links between Trump aides and Russian officials.
