Rep. Frank WolfFrank Rudolph WolfVulnerable Republican keeps focus as Democrats highlight Trump Bolton could be the first national security chief to prioritize religious freedom House votes to mandate sexual harassment training for members and staff MORE (R-Va.) on Friday urged the Obama administration to ramp up its efforts to help persecuted religious minorities in Iraq.

"From this point forward, the administration should do everything in its power to prevent more Christians and religious minorities in Iraq from becoming victims of this genocide and make every effort to disrupt and repel ISIS," Wolf said.

Wolf suggested the Obama administration go beyond air-dropping humanitarian aid, such as water and food supplies to thousands of Yazidis, who are a group of ethnic Kurds, trapped in the Sinjar Mountains in northern Iraq.

"The actions announced by the president last night are a positive first step — but these initial actions can't be the only steps this administration takes," Wolf said. 

Wolf said the Obama administration could also appoint a special envoy for religious minorities in the Middle East as well as a senior administration official to coordinate the U.S. response to the violence in Iraq toward religious minorities. 

Hours before President Obama announced the airstrikes, Wolf sent a letter urging the president to stop the genocide. 

"Your conscience will haunt you long after you leave office," Wolf warned.
