The amendment has powerful bipartisan backing, sponsored by Reps. James Sensenbrenner, Thomas Massie and Zoe Lofgren, along with co-sponsors Reps. Conyers, Poe, Gabbard, Jordan, O’Rourke, Amash, and Holt. Having Sensenbrenner bring out this amendment is a big deal. This amendment would restore at least one aspect of the USA Freedom Act that was stripped out at the last minute under pressure from the White House. Sensenbrenner sponsoring this bill highlights that he's clearly not satisfied with how his own bill got twisted and watered down from the original, and he's still working to put back in some of the protections that were removed. Conyers is a powerful force on the other side of the aisle, whose support for the USA Freedom Act was seen by some as a signal that the bill was "okay" to vote on. Having both of them support this Amendment suggests that neither were really that satisfied with the bill and felt pressured into supporting it.
