RICHMOND, Va. (AP) — House and Senate Republicans proposed wholesale overhauls Monday to Gov. Bob McDonnell’s legacy transportation funding initiative just one day ahead of a drop-dead legislative deadline.

In the Senate, the amendment from the conservative sponsor of McDonnell’s original bill substitutes a 5.5 percent sales tax at the wholesale level to gasoline and diesel and scraps McDonnell’s proposed overall retail sales tax increase from 5 percent to 5.8 percent.
