WASHINGTON – U.S. Rep. Haley Stevens, D-Rochester Hills, added her voice Tuesday morning to those saying President Donald Trump should be impeached if it is shown he asked the Ukrainian president to investigate a political rival, Joe Biden.

"If investigations confirm recent reports, these actions represent impeachable offenses that threaten to undermine the integrity of our elections and jeopardize the balance of power within the federal government," Stevens said in a statement.

Stevens' statement comes the morning after two other Michigan Democrats who, up until now, had declined to endorse the idea of impeachment — U.S. Reps Rep. Elissa Slotkin of Holly and Debbie Dingell of Dearborn — moved closer to support of impeachment.

Dingell said impeachment is called for given the allegations against Trump. Slotkin, who like Stevens won what had been a traditionally Republican district and a district won by Trump in 2016, said that unless the Trump administration can somehow explain the allegation, she will support impeachment as well.

Trump is apparently accused in a whistleblower's report of asking, in a July 25 call, the Ukrainian president to investigate Biden — the former vice president and a leading candidate for the Democratic nomination to run against Trump next year — and Biden's son, Hunter, who was on the board of a Ukrainian energy company.

Trump has said the call was appropriate and has denied there was any link to military aid for Ukraine which, according to reports in the Washington Post and elsewhere, was ordered withheld just days before the call. The funding was later released.

Stevens' announcement means that all the Democratic members of Michigan's House delegation are supportive of impeaching Trump if the current allegations against him turn out to be true.
