Senate takes hard-line tack on Iran sanctions
Hawkish Republicans introduced their own bills as bipartisan alternative struggles to materialize.
Senate Republicans have run out of patience with Iran's defiance of its international obligations, setting up a possible partisan showdown over new sanctions.
Hawkish lawmakers introduced two bills late last week that take aim at Iran's ballistic missile program and alleged human rights violations. Both bills have been endorsed by the Senate leadership, which is evidently tired of waiting on a long-rumored bipartisan alternative that has so far failed to materialize.
