WASHINGTON: Senators are renewing calls for U.S. military aid to Ukraine after receiving a closed-doors briefing from senior Obama administration officials.
Republican Sen. Lindsey Graham reports the administration seeing Russia prepared to fight in Ukraine to prevent separatists from being overrun.
In contrast, he says, the U.S. does not have a strategy.
Graham says sanctions against Russia thus far haven not changed President Vladimir Putin's calculus.
Graham wants measures targeting Putin personally. And he says lethal aid should be provided to help Ukraine's military.
Republican Kelly Ayotte and Democrat Bill Nelson agree on military assistance.
Ayotte calls the Obama administration's failure to provide weapons "shameful."
President Barack Obama does not believe U.S. military involvement is necessary.
