Former Democratic Ohio Governor Ted Strickland is is accusing Republican Presidential candidate Mitt Romney of being secretive and says he should release more tax returns. Speaking with reporters during President Obama's visit to Mansfield Wednesday, Strickland questioned whether Romney was hiding something from the American people. Republican Ohio House Speaker Bill Batchelder has also suggested Romney would do well to release the forms. Strickland, an Obama campaign co-chair, expects Ohio's overturned collective bargaining law to be a factor in the November elections because Romney supported the restrictions overwhelmingly rejected by voters in 2011. The former Governor spoke over shouts from a dozen demonstrators across the street.
