US President Donald Trump has agreed to a request from Defense Secretary James Mattis to propose a defense budget of $750 billion for the coming year, marking a reversal from plans to shrink defense spending, an administration official confirmed to CNN.

The agreement on the $750 billion budget came out of the meeting last Tuesday, which was attended by Trump, Mattis and the chairmen of the House and Senate Armed Services committees, Rep. Mac Thornberry, R-Texas, and Sen. James Inhofe, R-Oklahoma.

"The President fully supports the National Defense Strategy and continuing to rebuild the military," the official said. "With the help of Sen. Inhofe and Chairman Thornberry, President Trump agreed to $750 billion topline."
