The Indianapolis Star has the play by play:

The removal of two Republican election workers from a Warren Township polling site - for using improper methods to challenge voters' rights to cast a ballot - has prompted local Republican Party leaders to issue a statement of regret. The two officials - an official challenger and a clerk - were removed by unanimous vote of the Marion County Election Board.

The officials were reportedly challenging voters with information obtained through party affiliation reports, which is not one of the accepted challenges such as a person's address, age or lack of ID.

"We were disappointed to hear of the incident regarding these two workers. The Marion County Republican Party was not aware of these alleged activities, nor did the Party instruct any worker to engage in such behavior," Marion County Republican Party Chairman Tom John said in a statement issued at 2 p.m.
