A Kansas legislator is standing by a comment he made in a letter comparing Planned Parenthood with a Nazi concentration camp.

Republican state Sen. Steve Fitzgerald of Leavenworth told

on Monday that he considers Planned Parenthood worse than the Nazi regime in Germany.

Speaking to 13 NEWS, Fitzgerald asked rhetorically to compare the number of deaths that happened at the Dachau camp versus how many abortions Planned Parenthood performed.

Planned Parenthood Federation of America President Cecile Richards called Fitzgerald's comments disturbing and said he should be ashamed.

Fitzgerald is a strong abortion opponent. He sent a letter to Planned Parenthood Great Plains last week after learning a donation had been made in his name.

He said in his letter on official Senate stationery that such a donation in his name was worse than "having one's name associated with Dachau."

The Planned Parenthood chapter tweeted a photo of the letter.
