There are currently talks about a possible government shutdown Trump is using as leverage to attempt delivering his promise on key campaign promises that have not yet come to fruition. The last shutdown lasted from Oct. 1 to 16.

Trump has also suggested that he will unveil a "massive" tax cut proposal on Wednesday.
