WASHINGTON (AP) — A key House investigator said Tuesday that Speaker Nancy Pelosi is “absolutely right” to hold back on impeachment proceedings against President Donald Trump.

House Intelligence Committee Chairman Adam Schiff sided with Pelosi, who said Democrats shouldn’t pursue impeachment unless overwhelming and bipartisan support exists for doing so. Her comments to The Washington Post riled some liberals, including new lawmakers who helped flip the chamber to Democratic control.

Together, Pelosi and Schiff’s remarks are designed to signal to outspoken Democrats in the House that senior lawmakers aren’t behind any drive to impeach Trump. The delicate issue returned to the surface after a week of ugly dispute in Pelosi’s ranks over how to word a resolution condemning anti-Semitism and anti-Muslim discrimination.

Schiff, whose committee has been investigating Russian interference in the 2016 election, told reporters an impeachment effort seen as partisan would be doomed.

“A bipartisan process would have to be extra clear and compelling,” he said. “I think the speaker is absolutely right. In its absence, an impeachment partisan becomes a partisan exercise doomed for failure. And I see little to be gained by putting the country through that kind of wrenching experience.”
