President Donald Trump's budget for the 2019 fiscal year surpasses $US4 trillion and seeks big increases in money to combat the opioid epidemic and billions for his long-promised border wall.
The budget was written before last Friday's budget pact, making the fiscal plan being released on Monday all but irrelevant.
In a preview of the 2019 budget, the White House says it will ask for a $US13 billion increase over two years for opioid prevention, treatment and long-term recovery.
Trump also is requesting $US23 billion for border security, including $US18 billion for a wall along the US-Mexico border. In addition, the money would pay for more detention beds for detained immigrants.
Border security funding may well depend on legislation dealing with young immigrants brought to the country illegally as children.
