CONCORD, N.H. (AP) — Though some have been more outspoken than others, all four members of New Hampshire's congressional delegation now say they oppose a bill that would require shoppers to pay sales tax for online purchases.

The bill, which is expected to be voted on Monday in the Senate, would allow states to require online retailers to collect state and local sales taxes and send the money to the state where a shopper lives.

Sens. Kelly Ayotte and Jeanne Shaheen and U.S. Rep. Annie Kuster all have publicly opposed the bill, with Ayotte in particular playing a leading role.

U.S. Rep. Carol Shea-Porter has not publicly come out against it, but her spokesman says that she will vote against the legislation if an amendment protecting New Hampshire retailers fails.
