President Donald Trump is on the cusp of being impeached by the Democrat-controlled House of Representatives, with a historic vote set today on whether to formally accuse him of abusing his power in dealing with Ukraine to help himself politically, and then obstructing Congress by blocking their investigation. Trump lashed out directly at the vote on Tuesday, calling the proceedings to remove him from office an “attempted coup.” Should the House approve either of the articles of impeachment, the Republican-controlled Senate will hold a trial with all 100 senators acting as jurors, with a two-thirds supermajority — 67 votes — required to convict. Meanwhile, thousands of protesters in favor of impeaching Trump took to the streets Tuesday in cities across the country. On what many are calling “Impeachment Day,” we go to Capitol Hill to speak with Rep. Al Green of Texas, who was the first congressmember to call for President Trump’s impeachment from the floor of the House of Representatives in 2017.
