Billionaire left-wing mega-donor Tom Steyer is urging Democrats to use their new majority in the House of Representatives to impeach president Donald Trump.

Steyer spent over $100 million and employed over 1,000 people to make the case for impeachment throughout the 2018 midterm elections. Now, he argues in a New York Times op-ed printed November 8, newly-elected Democrats must live up to their end of the bargain:

As President Trump continues to accelerate his lawlessness, the new Democratic House majority must initiate impeachment proceedings against him as soon as it takes office in January. For nearly two years, Mr. Trump has publicly flouted his oath of office. He has turned the presidency into a moneymaking enterprise for a family business he refuses to divest from, in direct violation of any plain reading of the Constitution. He is all but an unindicted co-conspirator in two federal felony cases. He has created an atmosphere of criminality through his hateful, violent rhetoric against political opponents, journalists and private citizens alike. Most egregiously, he has a longstanding pattern of obstructing justice. On Wednesday, he continued this by firing Attorney General Jeff Sessions and installing Matthew Whitaker — who has publicly called for curtailing the special counsel’s investigation — as acting attorney general, sparking a constitutional crisis that threatens the rule of law itself. As the list of Mr. Trump’s impeachable offenses — at least nine and counting — has grown, more than 6.2 million people across the country have signed a petition, created by my organization Need to Impeach, demanding that their representatives confront his lawlessness. For months, public support for impeaching the president has been roughly equal to what it was before Richard Nixon resigned.
