Senate Republicans are expected to bring two bills to a full floor vote on Wednesday: one aimed at addressing how data centers drive up utility electricity prices, and another that would bar members of Congress from trading individual stocks while in office.

Republicans are hoping to score a messaging victory with these two bills ahead of the November midterm elections.

Senate Democrats, including Minority Leader Chuck Schumer of New York, have criticized both measures, saying the data center bill lacks teeth and the stock trading ban falls far short of meaningful reform.

The Senate is poised to secure a series of messaging wins before beginning its election recess and sending lawmakers back to their home states.

Republicans are forcing Democrats through procedural votes on Wednesday on two bills: one designed to tackle the electricity cost burden created by artificial intelligence data centers, and another to restrict members of Congress from profiting from the stock market while serving.

With Democrats firmly opposed, both bills are unlikely to clear the Senate's 60-vote filibuster threshold. Wednesday may be the final legislative day before the Senate breaks for more than a month of election recess.

Democrats have been attacking the data center bill previously passed by the House. The bill cleared the House earlier this month by a vote of 417 to 3. It would establish a regulatory framework that states could optionally adopt, requiring large AI data centers to bear the cost of supporting energy infrastructure themselves rather than passing those costs on to ordinary ratepayers.

Senate Minority Leader Chuck Schumer, a New York Democrat, said on the Senate floor Tuesday that the proposal is a "non-binding show bill." "This bill is a sham. The entire flaw of the Republican data center bill can be summed up in one word: non-mandatory," Schumer said. New Mexico Democratic Senator Martin Heinrich, the top Democrat on the Senate Energy and Natural Resources Committee, expressed similar concerns. Earlier this month, Ohio Republican Senator Jon Husted sought unanimous consent to fast-track the bill, but Heinrich blocked it. Husted is in a competitive re-election race against former Democratic Senator Sherrod Brown. Brown has accused Husted of promoting data center projects in the state during his time as lieutenant governor.

In recent months, AI data centers have become a hot election issue, with opponents demanding stricter constraints on developers, prompting Husted and other Republicans to seek a messaging win through the data center bill.

The second bill, called the Stop Insider Trading Act, previously passed the House by a vote of 232-198. It would prohibit sitting members of Congress from buying individual stocks but would not force lawmakers to divest their existing stock portfolios — a sticking point for some Democrats who advocate for a stronger trading ban.

Republicans also attached a highly controversial voter ID provision to the bill, which Democrats broadly oppose. Schumer also criticized the stock trading bill on Tuesday, calling it a "theatrical farce" and the voter ID attachment a "poison pill amendment." "The bill Republicans have put forward is full of holes, one after another. This is a step backward when it comes to solving this critical issue," Schumer said. Husted posted on X on Tuesday that both proposals are "common-sense bipartisan bills." "Lowering energy costs, requiring photo ID to vote, and banning members of Congress from trading stocks could have been bipartisan achievements," Husted wrote. "Now it is Senate Democrats alone who are blocking the policies the American people want."
