The US election is a shot at Trump's $1.5 trillion budget.
Democrats, who hold majorities in both houses of Congress, oppose Trump's request for a $1.5 trillion military budget and have said they will block any attempt to advance it.
According to Bloomberg, opposition from Democrats could increase some of Trump's military ambitions, including the Golden Dome missile shield and the Trump-class cruiser program.
The sources added that the Democrats do not want to be seen as supporting a war budget against Iran and will probably only approve a military budget of about a trillion dollars.
