CBNNews.com - Several Republican congressmen are criticizing their colleagues for taking a trip to Havana this week.

They say those who went to Cuba ignored the rights of Cuban political prisoners.

 Congressman Frank Wolf criticized the Obama administration's move to liberalize relations with the communist regime.

"This administration ought to be very, very careful.They ought not lift sanctions unless the prisoners are released. It will be a moral issue if they do," Wolf, R-Va., said.

The Republican congressmen say the Castro regime has repeatedly denied them visas to visit political prisoners and the families of prisoners in Cuba.
