"I rise today with a sense of responsibility and duty to the people who have elected me, a sense of duty to this country, a sense of duty to the Constitution of the United States of America," he began. "I rise today, Mr. Speaker, to call for the impeachment of the President of the United States of America for obstruction of justice."
"There is a belief in this country that no one is above the law. And that includes the President of the United States of America."
The goal of this is to get Republicans to explicitly reject impeachment at this stage in the proceedings. That becomes extremely useful cannon fodder later on down the line.
