NASHVILLE (AP) - Opponents of a Vanderbilt University policy banning discrimination in student groups want to enact a law to strip the private school of its police powers if it doesn't change its ways.

The bill sponsored by Sen. Mae Beaver of Mt. Juliet and fellow Republican Rep. Mark Pody of Lebanon was the subject of competing press conferences at the Legislative Plaza in Nashville on Tuesday.

Republican Gov. Bill Haslam last year vetoed a bill to do away with Vanderbilt's "all comers" policy, which requires student groups at the school to allow any interested students to join and run for office. Religious groups argue the policy forces them to accept students who don't share their beliefs.

Haslam said he disagrees with Vanderbilt's policy, but opposes targeting a private institution.
