President Donald Trump released the blueprint for his proposed budget this week and it has already increased the likelihood of a government shutdown as parties argue over details.
Lawmakers in Congress have until April 28 to either pass a spending bill to fund the government, or run the risk of shutting down the government.
Democrats have begun talking about "deal breakers" and "poison pills" within the legislation that would make it impossible for them to support.

"If they put those poison pill amendments in and try to shove them down the American people's throats, of course they might be responsible for shutting the government down," Senate Majority Leader Chuck Schumer said at a press conferences this week.
Democrats complain they cannot support measures like defunding Planned Parenthood and starting a deportation force, and that Republicans must be willing to break with Trump on some of those issues if they want to keep the lights on.
Republicans have pushed back, saying the Democrats must be willing to play ball and accept the new leadership in Washington.
"I'm amused by the Democrats apparently warming up to the idea that threatening to shut down the government is a good idea. It seems to me everybody's got kind of memory loss on the other side," McConnell said.
The last major government shutdown occurred in October of 2013 when a lack of funding forced the federal government to cease all non-essential activities for a little over two weeks.
The longest government shutdown came in the mid 1990s when President Bill Clinton vetoed a Republican-backed budget bill, forcing the government to shut down twice leading into the Thanksgiving holidays of 1995 and following Christmas. Those shutdowns lasted for a total of 27 days.
