Pelosi says impeachment is about 'urgency' not speed

"This is about patriotism," Pelosi said. "If we allow one president, any president no matter who she or he may be to go down this path, we are saying goodbye to the Republic and hello to a president king. That is what is at stake in this impeachment as well."

Democrats in the U.S. House of Representatives announced formal impeachment charges against Donald Trump on Tuesday, setting the stage for a battle in the Senate that the White House said would fully exonerate the Republican president.

The two formal charges, or articles of impeachment, accuse Trump of abusing power in his effort to pressure Ukraine to probe a political rival and then obstructing Congress' investigation into the scandal.

The Democratic-controlled House is almost certain to vote to impeach the president. It could take up the matter next week. A trial would then be held in the Republican-controlled Senate, likely in January. No Republican in either the House or Senate has come out in favor of Trump's removal from office.
