The House of Representatives has the power to impeach the President and other officials. Johnson and Clinton were impeached by the House but not convicted by the Senate. Nixon resigned before he could be impeached.
The House has voted on three resolutions to impeach President Trump, special resolutions as I understand it. All three have been colossal failures with wide margins voting no. That suggests that the mood to impeach comes only from relatively few, not the massive margin needed to impeach.
