The Senate is expected by 5:30 p.m. to vow on two amendments to the Federal Aviation Administration (FAA) authorization bill.

One vote will be on an amendment from Sen. Rand Paul (R-Ky.) to exempt infrastructure projects under the FAA from having to pay prevailing wages. The second is an amendment from Sen. Sheldon Whitehouse (D-R.I.) that would make it a crime to aim laser pointers at aircraft.
