Gay rights groups are trying to bar Pastor Greg Laurie from events at the National Day of Prayer because of his biblical stance on homosexuality.
The Southern California pastor is set to lead prayer on Capitol Hill and at the Pentagon.
Now, a military group that supports gays says Laurie should be barred from the Pentagon because he has said that the Bible calls gay sex sinful.
Outserve SLDN says Laurie's appearance would be wrong since gays can now openly serve and even get married in some military chapels.
The Human Rights Campaign says the pastor shouldn't be allowed on Capitol Hill, either.
A spokeswoman for Laurie says he still plans to attend the events.
