According to Stars and Stripes:
Ted Cruz and Marco Rubio are supporting legislation that could put the brakes on women in the military draft, adding momentum to growing opposition on Capitol Hill.
The Republican presidential candidates confirmed Thursday that they will back Sen. Mike Lee, R-Utah, and his upcoming bill barring the White House or the courts from changing the law, which requires only men to register with Selective Service in case they need to be drafted into combat.
A bipartisan bill was introduced in the House on Thursday that would completely abolish the draft.
