Democratic and Republican senators say the U.S. should offer a home to more Syrian refugees.
Syria's civil war is now in its third year. More than 2 million have fled the Arab country, straining neighboring Iraq, Jordan, Lebanon and Turkey. Many live under awful conditions.
U.S. aid totals $1.3 billion. But the U.S. has resettled about 100 Syrian refugees since fighting began.
Democratic Sen. Dick Durbin lamented the figure may only rise to a few hundred this year. He criticized overly restrictive U.S. immigration laws for refugees.
Republican Sen. Ted Cruz, whose father was born in Cuba, also highlighted the crisis, citing the plight of Christian refugees.
U.S. officials cited procedural delays. They said far more refugees could arrive in 2015.
