When the White House releases its budget on Monday, it will also release an addendum that provides a blueprint for how to utilize the higher spending caps, the senior OMB official said.

"It will include additional [fiscal 2019] funding for a limited set of Administration priorities as well as proposals to fix certain budget gimmicks used to circumvent the spending caps," the official said.

The budget deal also raised the spending caps for the current fiscal year. The OMB official said that, separately from its budget request and addendum, the administration will provide recommendations to Congress about how to use the higher spending caps for this year.
