The number of Democrats who have called for the House to launch impeachment proceedings against President Trump continues to grow, with support swelling to an all-time high in the wake of special counsel Robert Mueller's rare public statement last month.

The state of play: Nearly than 80 House Democrats — and a single House Republican — have publicly expressed support for opening an impeachment inquiry, according to an Axios count. Speaker Nancy Pelosi, the one House Democrat who matters most, has continued to insist that impeaching Trump would be premature, especially without the support of the Republican-held Senate. Whether she will be able to maintain that stance as divisions grow within her caucus remains to be seen.

The lone Republican: Rep. Justin Amash (Mich.) became the first and only Republican in Congress to call for Trump's impeachment in May.
