A small, previously obscure federal ethics office has catalogued a burst of inquiries and complaints from the public — more than 30,000 — since Donald Trump’s election as president, compared to a few hundred in all of fiscal 2015.

The huge increase in public outreach to the Office of Government Ethics reflects an administration with unprecedented corporate entanglements and an outwardly blase approach to ethics statutes and the truth, as well as a flair for scandal and drama.

But the rise is also evidence of a mobilized opposition movement that has put ethics and fighting corruption at the center of its attacks. Democrats on the Hill, motivated by a resist-Trump, grass-roots movement around the country, aim to weaken the president’s power and thwart his administration’s policy agenda at every turn — if not force him out of office.

The taking down of a president is a long shot, especially for the minority party with its limited procedural tools and near total inability to set the congressional agenda or to hold oversight hearings. While the strategy isn’t risk-free for Democrats, it could set up their party for future electoral gains.

“Democrats are, No. 1, trying to rouse their base and their troops for the midterm elections and then in 2020,” said Barbara Perry, director of presidential studies at the University of Virginia’s Miller Center.
