GLEN RIDGE, N.J. (AP) — Some schools no longer want to serve as polling places since the 2012 massacre at Sandy Hook Elementary School in Connecticut.

A presidential commission is hearing from election officials who are worried about schools trying to move balloting out of their buildings because of security concerns.

The commission plans to make recommendations this month to President Barack Obama about ways to improve access to the polls. The commission has signaled that it intends to encourage schools to stay open for voting.

Some states require schools to be available on Election Day, although there was an effort in at least seven states in the past year to allow schools to close. None of the bills passed.
