constitution. a separation of powers. three coequal branches, each a check and balance on the other. the president has engaged in abuse of power undermining our national security and jeopardizing the integrity of our elections. i am asking our chairman to begin with articles of impeachment. >> it's something i do not think we have ever seen before. a president who has doubled down on violating his oath to faithfully execute the laws and to protect and defend the constitution. >> president trump has committed impeachable high crimes and misdemeanors by corruptly abusing the office of the presidency. >> after reviewing the evidence that's been made public, i cannot help but conclude that this president has attacked each of the constitution's safeguards against establishing a monarchy in this country. if what we're talking about is not impeachable then nothing is.
