A coalition of right-wing ¡°constitutional sheriffs,¡± who claim legal power in their jurisdictions that exceeds U.S. federal and state authorities, has a new calling: investigating conspiracy theories that the 2020 election was rigged against former U.S. President Donald Trump.

The Constitutional Sheriffs and Peace Officers Association has teamed up with True the Vote, a Texas nonprofit and purveyor of debunked voter-fraud claims, to recruit like-minded sheriffs nationwide to investigate allegations the 2020 U.S. election was stolen and to more aggressively police future voting.

The partnership, detailed last week at the association¡¯s annual gathering in Las Vegas, aims to intensify a movement already underway. At least four ideologically aligned county sheriffs in the states of Michigan, Wisconsin, Kansas and Arizona have launched election-fraud probes since the 2020 vote. None has established evidence of systemic fraud.
