INDIANAPOLIS (AP) _ A couple hundred activists have filled the Indiana House of Representatives chamber before lawmakers consider a proposed constitutional ban on gay marriage.

Opponents of the ban showed up in force Wednesday afternoon, wearing red shirts to signal their opposition to the proposed constitutional amendment.

Republican House Speaker Brian Bosma announced Tuesday that he was moving the proposed ban and a companion measure to the House Elections Committee at the request of GOP lawmakers who wanted to vote on the issue. The measure stalled in the House Judiciary Committee last week amid concerns from a few Republican committee members.

Legislators approved the proposed amendment with broad bipartisan majorities in 2011. But a shift in public attitudes combined with a strong campaign by opponents has spurred apprehension among many lawmakers.
