ASHE SCHOW: These senators still have not answered questions about their campus sexual assault bill.

To date, I have only heard from two offices: Sens. Marco Rubio, R-Fla., and Chuck Grassley, R-Iowa. I have sent multiple e-mails to the offices for the remaining co-sponsors and have not received answers.

No one has responded for Sens. Kelly Ayotte of New Hampshire, Richard Blumenthal of Connecticut, Dean Heller of Nevada, Claire McCaskill of Missouri or Mark Warner of Virginia.

Additionally, Glenn Kaplan, a spokesman for Sen. Kirsten Gillibrand, D-N.Y., did contact me and offered to walk me through the bill, but wouldn’t simply answer the questions that Rubio and Grassley’s spokespeople answered.

If this bill is such a great opportunity to address the issue of sexual assault on college campuses, why aren’t these senators jumping at the chance to talk about it?

Perhaps they’re having second thoughts.
