Here is how to follow the impeachment debate and what to watch for.
Where to Watch
The impeachment proceedings can be streamed online on several platforms, including the House clerk’s website, C-SPAN and YouTube. The New York Times will also provide video of the hearing with live analysis from reporters beginning at 9 a.m.
Those watching on television can find the proceedings broadcast in full on several networks, including CNN and PBS.
What to Watch For
Democrats appear to have more than enough support to vote to impeach Mr. Trump. But the breakneck pace at which they have moved ahead with the vote has left some Republican lawmakers prevaricating and proposing alternate solutions, like a bipartisan measure to censure the president.
Several House Republicans, including Representatives John Katko of New York and Liz Cheney of Wyoming, the party’s No. 3 in the chamber, have said that they would join Democrats in support of impeachment. Several more who have not publicly discussed their stances are expected to do the same on Wednesday.
