House Minority Whip Steny Hoyer, D-Md., argued Tuesday that calls for the impeachment of President Trump are premature and that conclusions from ongoing investigations need to be reached before that step is taken.

"I think it's too early to talk about impeachment," Hoyer said. "However, it is past time to be greatly concerned for our country."

He said that a day after two more House Democrats, Rep. Al Green, D-Texas, and Rep. Sheila Jackson Lee, D-Texas, raised the possibility of impeachment.

"We need to know the facts, and that's why we need to do an in-depth investigation, either through a commission, which I think is appropriate, [or] a special prosecutor. I am hopeful that both the Senate and the House Intelligence Committees will do their work in a responsible, serious, complete and in-depth way," Hoyer said. "So as we proceed there, there will then be time to make a determination as to whether further action is necessary."

"Impeachment is a very serious matter," Hoyer said. "And it ought not to be taken lightly. It ought not to be taken politically. It ought to be taken based upon very substantial facts. That's what's happened in Watergate... very substantial investigation."

On Monday, House Minority Leader Nancy Pelosi, D-Calif., agreed that facts are needed before any further steps are made in that direction.

"Leader Pelosi and I have taken the same position, which is... if the facts warrant, there will be time to talk about that," Hoyer said. "But we need to get the facts first."
