There are reports, attributed to a senior administration official, that President Barack Obama is reconsidering whether to send lethal assistance to Ukraine.
It follows an upsurge in violence in Eastern Ukraine in recent weeks.
But the source says he remains concerned about the risks of a proxy war with Russia.
The U.S. has so far limited its military aid to non-lethal help, such as gas masks and vehicles.
US State Department spokeswoman Jen Psaki says that while no option is off the table, the US continues to focus on a political and diplomatic solution.
