Senator Mitch McConnell, the Republican majority leader, released draft rules on Monday. They would limit each side’s arguments to 24 hours over two days and permit the Senate to decline to hear new evidence.

Mr. McConnell has said the rules are based on those used during President Bill Clinton’s impeachment trial in 1999, but there are meaningful differences.

News analysis: Mr. Trump’s lawyers have said that the articles of impeachment — for abuse of power and obstruction of Congress — are invalid because they don’t accuse him of an ordinary crime. It’s an argument that plenty of scholars have rejected, our Washington correspondent explains.

The details: Read the brief that Mr. Trump’s legal team submitted to the Senate on Monday. The House has until noon to file a rebuttal.
