House Judiciary Committee Chairman Jerry Nadler will miss the last procedural step in the chamber’s impeachment process to tend to a family emergency.

The House Rules Committee is scheduled on Tuesday to set the terms of the House’s upcoming floor debate ahead of voting on the two articles of impeachment against President Trump. Nadler, however, is away from Congress, because his wife Joyce Miller is ill. The New York Democrat is expected to return to Washington, D.C., late Tuesday or early Wednesday before the full House’s impeachment vote.
