Senate Majority Leader Chuck Schumer (D-N.Y.) has set a Wednesday test vote for a national security spending bill that may not be able to pass, as AP reported.

The text of the bill, which includes immigration measures and provides aid to Ukraine, Israel and Taiwan, is expected to be released today or this weekend, CQ reported. Negotiators have worked on the border security component for months as a way to pass the foreign aid.

Many Republican lawmakers are skeptical of the bill, and some think Schumer’s timeline is too fast.

“If Schumer tries to jam this in next week… I think that makes things a lot more complicated,” Sen. John Cornyn (R-Texas) said, according to CQ. “And I think it creates a lot more jeopardy for the final product.”
