The House GOP leadership has been facing pressure from conservative members of their party to include language in the defense bill that would prevent President Obama from closing Guantanamo Bay detention center. The conservatives also want to restrict the president's ability to transfer detainees to other countries and impose stricter conditions on those who are released.

Some experts argue that this demand could lead to a showdown between Congress and the White House, as President Obama has made clear his intention to close the prison at Guantanamo Bay. The defense bill is expected to come up for a vote next week, and it remains unclear how the leadership will handle these demands from conservative members of their party.
