Democrats have been careful not to use the word “impeachment” even as special counsel Robert Mueller drops indictments and details emerge on President Trump’s potential conflict of interests. But what happened in Helsinki on Monday is testing their patience.

Democrats in and outside Congress unleashed a torrent of statements calling Trump’s remarks alongside Russian President Vladimir Putin “treasonous,” “disgraceful,” and “treacherous.” On Tuesday, House Democrats increased the drumbeat, planning to bring a resolution to the floor rebuking Trump and confirming the chamber’s position in support of the U.S. intelligence community’s conclusion that Russia interfered in the 2016 presidential election, attacking multiple facets of the Democratic Party in an effort to sway the election.
