At this time of year, newly introduced legislation often is introduced and then quickly enters oblivion. I checked this Senator's committee and subcommitee assignments and did not find any direct link to federal contracting. Maybe that explains it.

"Sen. Toomey's bill would require the GAO to include the most common reasons bid protests are sustained. This additional information could help federal agencies identify needed improvements in the contracting process, reduce the number of protests overall and provide Congress with much-needed information about possible weaknesses in the federal contracting process to facilitate potential legislation."
