CHEYENNE, Wyo. (AP) — Sen. Mike Enzi says he's planning to vote against a likely Senate resolution to authorize a strike on Syria.

Senate Majority Leader Harry Reid had been planning a vote Wednesday. Reid now says there's no need to rush, especially during international talks over what to do about Syria's chemical weapons.

President Barack Obama advocates an attack to deter the Syrian government from using chemical weapons against rebels. The administration says a gas attack by government forces Aug. 21 killed hundreds of civilians.

Enzi said Monday he hasn't received good answers to what objective a U.S. attack would accomplish or what U.S. interests that would serve.

Liz Cheney also says she would not vote to authorize force in Syria. Cheney is opposing Enzi in next year's Senate race.
