Over three weeks after the House of Representatives approved charges of abuse of power and obstruction of Congress against President Donald Trump, House Speaker Nancy Pelosi said Thursday that she remains in no rush to officially trigger an impeachment trial in the Senate, again pressing GOP leaders to define how they will structure that trial.

"I'll send them over when I'm ready," Pelosi said at a Capitol Hill news conference. "And that will probably be soon."

Pelosi rattled off a series of items which have become public since the House votes, making the case that the Senate needs to hear from witnesses who did not testify before the House impeachment investigation, something which GOP leaders have resisted.

"We need to see the arena in which we are sending our managers. Is that too much to ask?"

Pelosi's remarks came as some Democrats in both the House and Senate began to publicly say that she should send the articles of impeachment to the Senate.

On CNN, Rep. Adam Smith (D-WA) was asked on Thursday morning if it was time to send the impeachment charges to the Senate - and said it was.

A few hours later, he changed his tune, as did some Senate Democrats who had come out and said it was time for them to act on the impeachment matter.

The impeachment trial cannot officially begin until the actual papers are transmitted from the House to the Senate.
