Trump urges Republicans to block government funding if voter ID measure is removed from spending bill.

• If Congress cannot pass a strict voting bill, Donald Trump suggested that Republicans should push for a government shutdown as part of the temporary funding bill to keep the government running.
• Currently, House Speaker Mike Johnson, R-La., is attempting to pass a six-month stopgap funding bill along with the SAVE Act, a contentious legislative proposal that demands voters present proof of citizenship at the polls, which Democrats have stated they will reject.
• A funding deal must be reached by lawmakers before the government shuts down on Sept. 30.

On Tuesday, former President Donald Trump advised congressional Republicans to pursue a government shutdown if they cannot include a strict voting bill in the temporary funding bill that would keep the government running.

The Republican presidential nominee wrote on Truth Social that if Republicans in the House and Senate do not receive absolute assurances on election security, they should not proceed with a continuing resolution on the budget in any way, shape, or form.

"Illegal aliens are being attempted to be stuffed into voter registrations by the Democrats. Prevent this from occurring - shut it down!"

Currently, House Speaker Mike Johnson, R-La., is attempting to pass a six-month stopgap funding bill along with the SAVE Act, a contentious legislative proposal that mandates voters to present proof of citizenship at the polls.

Democrats in Congress have consistently indicated that they will not approve a funding bill linked to a contentious policy, which they view as a "poison pill" intended to derail the entire agreement.

"Senate Majority Leader Chuck Schumer, D-N.Y., stated on the Senate floor Tuesday that the House Republican CR is an unserious and uncooked product. He urged Republicans to collaborate with Democrats on a bipartisan package that includes input from both sides, avoids harmful cuts, and is free of poison pills."

A government shutdown may occur if Congress fails to reach a funding agreement by Sept. 30.

Despite Democrats' firm stance against the SAVE Act bill attachment, Johnson has remained committed to Trump's wishes and shown no signs of backing down.

Senate Minority Leader Mitch McConnell, R-Ky., is open to compromising with Democrats and breaking away from hardliners who insist on preserving the SAVE Act at all costs, even if it means a government shutdown.

McConnell stated on Tuesday that closing the government is never a good option.

The SAVE Act was included in the rule for the CR, which was approved by the House that day, funding the government until March 2025.

Even if the House passes the funding bill on Wednesday, it will be dead on arrival in the Democratic-controlled Senate.
