Court hearings are wrapping up in a case involving a public school holding graduation ceremonies in a church.

The American Civil Liberties Union (ACLU) claims it is an unconstitutional endorsement of religion, and two Connecticut high schools are being sued.

More school districts have been using churches for graduation because sanctuaries can seat a lot of people, and it's an affordable alternative to other venues.

The church has offered to cover up religious symbols like crosses during the graduation.

"There really isn't much to see outside, everything inside the board and the bishop have agreed to cover up that's problematic," Connecticut School Board member Vincent McCarthy said.

"There are many comparable, and affordable secular locations within the same vicinity as the church," Andrew Schneider, with the ACLU said.

The graduation ceremonies are less than a month away, and the judge's decision is expected next week.
