"As an elected leader, I'm all too aware of government's limitations when it comes to fixing things that are spiritual in nature. That's where prayer comes in and we need it more than ever."
Annie Laurie Gaylor is the president of The Freedom From Religion Foundation and says it's not right for Perry to endorse a
specific day of prayer.
"He has been criticized by many groups, including ours. We asked him to rescind the proclamation and we go no response.
It's been two months of kind of rabid evangelical promotion by the governor's office and we decided we had to go to court."
Gaylor says it's unfair to groups like hers to have a public official leading a clearly religious event.
"We are a competing group with churches and with the American Family Association and here the governor is preferring them and their branch of Christianity over other religions and over us. That's not right. That's not what was intended by our secular founders."
A representative from the prayer event, in a written statement, said "This kind of legal harassment is no surprise, but we will vigorously defend the rights of Americans to assemble and pray and we will win."
