WICHITA, Kan. (AP) — The Democratic challenger to Kansas Secretary of State Kris Kobach has released the past three years of personal income tax information and is challenging her opponent to do the same.

Jean Schodorf released her return transcripts on Wednesday in a bid to force Kobach to prove his claim that he spends only an average of 4.9 hours per week on his private law practice. Critics contend Kobach spends too much time outside Kansas as the architect of anti-immigration laws across the nation.

Kobach says he has already made public how much time he averages in his private law practice and calls Schodorf’s move a political stunt.

Schodorf’s returns listed total annual income ranging from $51,128 to 136,098. Her federal income taxes ranged between $2,374 and $18,234 during those three years.
