Sibley challenges opponent's eligibility in Senate race

Republican David Sibley of Waco, trying to recapture the senate seat he gave up a decade ago, is challenging the eligibility of perhaps his strongest opponent in a special election that will be held for the now vacant post on May 8. Sibley contends that fellow Republican Brian Birdwell of Granbury, a retired lieutenant colonel in U.S. Army, cannot serve in the Senate because he does not meet the constitutional requirement of five years of continuous residency in Texas to run.
