House Majority Leader Steny H. Hoyer, a Maryland Democrat, and Minority Whip Steve Scalise spent more than an hour on the House floor Friday afternoon engaged in a spirited debate over the House impeachment inquiry into President Donald Trump. The two lawmakers meet on the floor weekly to discuss their caucuses’ legislative agenda. Friday’s exchange was a stark departure from the more congenial tone in their fly-out day conversations.

The verbose back-and-forth between the senior congressmen began with a question from Scalise, a Louisiana Republican, on the process for impeachment. The conversation then turned to cover a wide range of arguments on impeachment in the House including:

• [7:45] Process and rules of the impeachment inquiry
• [13:17] Rep. Devin Nunes, the top Republican on the House Intelligence Committee
• [16:02] Foreign interference in U.S. elections
• [23:42] The Mueller report
• [28:50] Trump’s call with Ukrainian President Volodymyr Zelenskiy
• [31:50] Russia, Iran and Syria
• [36:10] Historical precedent
• [42:27] The Bidens
• [45:20] White House Acting Chief of Staff Mick Mulvaney
• [51:34] Legislative gridlock in the Senate
• [57:10] Government shutdown
