Washington: President Barack Obama made a rare visit to the Pentagon to get an update from military leaders on the campaign against the Islamic State.
Obama's meetings with top defense officials and other national security advisers follow a wave of weekend airstrikes by the US-led coalition in eastern Syria. The coalition says it was one of the most sustained aerial operations carried out in Syria to date.
Ahead of Obama's meetings, the White House sharplycriticized Senate Republicans for failing to confirm Adam Szubin, Obama's nominee to be the Treasury undersecretary responsible for choking off funding to groups like IS.
White House spokesman Josh Earnest said Republicans had refused to "even give him the time of day for a hearing" since Obama nominated Szubin in April, adding that the Senate should confirm him before lawmakers go home for their annual August recess.
The president has insisted he will not send U.S. troops into combat to fight the Islamic State in Iraq or Syria. However, he has acknowledged that the US lacks a "complete strategy" for training Iraqi troops to carry out ground missions.
Efforts to train Syrian rebels are also sputtering. Fewer than 100 rebels are being trained by the US, far fewer than the goal of producing 5,400 fighters a year.
