Texas Republican Rep. Brian Babin is collecting signatures on a letter he plans to send to House Speaker Nancy Pelosi to request that every member of the House be required to stand and cast their votes vocally on the Democratic resolution on the impeachment inquiry.

This would be instead of using the electronic voting machines the chamber uses for roll call votes.

In the letter, Babin claims that the electronic voting system "shields Members from having to stand before their colleagues, their constituents, and the world to announce their decision on such a momentous matter in their own voice."

To be clear, this is just a difference in optics: A vote has the same weight either way.

Asked about Babin’s letter, official congressional historians told CNN that they couldn't find another instance of the House intentionally taking a roll call vote without the electronic system since it was first installed in January 1973 — although the House has had to vote without it during malfunctions in the system. The last major outage was in the early 2000’s.

The historians also said after reviewing their materials that there isn’t evidence of any similar procedural push during the Clinton impeachment.
