Arizona Sen. John McCain, a Russia hawk and occasional Donald Trump critic, blasted a report on the administration's new Syria posture just hours after revealing he had a cancerous brain tumor. McCain's statement faulted the administration for reportedly ending a covert program begun during the Obama administration to provide arms to Syrian rebels battling President Bashar al-Assad. 'If these reports are true, the administration is playing right into the hands of Vladimir Putin,' the Armed Services Committee chairman said in a statement.
