A controversial proposal to allow firearms on university campuses in New Hampshire remains uncertain after divisions emerged between Republicans in the State House and Senate.

Earlier this year, the House passed House Bill 1793, which would remove firearm restrictions for students and staff at public colleges and universities.

But Senate Republicans approved a scaled-back version on Thursday that would only allow faculty members to carry concealed firearms on campus.

A separate last-minute effort by House Republicans to revive the broader proposal also failed.

Democrats in both chambers have strongly opposed the legislation, arguing it could increase safety risks for students and staff. University leaders, police chiefs and students have also voiced concerns.

According to testimony presented to the Senate Judiciary Committee, nearly 1,900 people opposed the bill, while 92 supported it.

Critics argued firearms on campus could make mass shooting responses more difficult and increase the risk of alcohol-related incidents and suicides.

Supporters, however, said the bill would strengthen self-defence rights for students walking alone at night.

The future of the legislation is now expected to be decided during negotiations between the House and Senate later this year.
