Washington (CNN) Sen. Rand Paul doesn't like Congress' omnibus spending bill, and he wants you to know it.

The Kentucky Republican tweeted throughout Thursday passages from the $1.3 trillion spending bill to keep the federal government running through September, along with his criticism of the proposals, ahead of the shutdown deadline Friday at midnight.

While there's still a day until government funding runs out, Paul has sent a lengthy series of tweets criticizing the omnibus. Lawmakers are watching him to see if he'll enforce Senate timing protocols that would drag the vote beyond the shutdown deadline.

"Well here it is, all 2,232 budget-busting pages. The House already started votes on it. The Senate is expected to soon. No one has read it. Congress is broken..." he tweeted, along with a photo of himself holding the entire printed omnibus.
