Bloomberg Pressures Donors Over Gun Control Votes

NEW HAVEN, Conn. (AP) -

Mayor Michael Bloomberg is stepping up his gun control campaign by asking donors not to support four Democratic senators who opposed a bill to expand background checks.

Bloomberg made the request in a letter to about 1,100 Democratic donors. It comes as a mayor’s group that he co-founded plans a national bus tour aimed at getting senators who voted against the proposed legislation in April to change their minds.

The tour leaves Friday from Newtown, CT, where a gunman six months ago killed 20 children and six adults at an elementary school.
