It's deadline day for Trump's Iran ultimatum

Hello readers, welcome back to Tuesday's On Politics. I'm Kathryn Palmer. Today is the deadline for Trump's ultimatum on Iran, one of the tensest days of his six-week war. Here's the latest.

It's deadline day for Trump's Iran ultimatum. What to know:

President Donald Trump issued a hard deadline over the weekend for an all-out attack on Iran, telling the regime to reopen the Strait of Hormuz or it will face targeted strikes on critical domestic infrastructure.

As the clock ticks down on his deadline on Tuesday, April 7, the president has doubled down on his threats to bomb Iranian power plants and bridges.

The president made similar threats before, starting on March 21, when he told Iran it had 48 hours to reopen the critical oil trading route or he would bomb power plants. But this one hasn't shown signs of being subject to the extensions he's issued in recent weeks, throwing down a gauntlet that could result in widespread attacks.

Experts and human rights groups have warned that his targets of bridges and power plants could violate international law and lead to civilian deaths. Trump has brushed off those concerns and today threatened that a "whole civilization will die tonight."

So far, the Iranian regime has not indicated it will meet the president's demands. As the 8 p.m. ET deadline creeps closer, USA TODAY is providing live coverage of the latest news and updates on Trump's potentially consequential ultimatum.

Trump's threat to Iran's infrastructure inflames MAGA tensions

The president's strongly worded Easter threat to blow up Iranian infrastructure has prompted prominent figures on the right to push back, further inflaming tensions within his MAGA base over Iran.

Former GOP Rep. Marjorie Taylor Greene even suggested Trump should be removed from office under the 25th Amendment to the U.S. Constitution. Prominent conservative commentator Tucker Carlson said Trump's post is "vile" on "every level." Other criticisms and unease have come from former GOP Congressman Matt Gaetz, Trump's initial pick for Attorney General, and Sen. Ron Johnson, a Wisconsin Republican and staunch Trump ally.

Polls show the Iran war is broadly unpopular, but most Republicans approve of how Trump is handling the conflict.

Democrats aim to take MTG's former GA seat

Democrats are angling for a blue wave in this year's midterm elections. One possible sign of how the party might perform could come in Georgia today, during a special election run-off for the seat last held by former MAGA firebrand Marjorie Taylor Greene.

Democrats' hopes are focused on Shawn Harris, a retired Army brigadier general, who believes the sinking economy, unpopular war with Iran and Trump's dipping approval numbers make the district ripe for a political upset, despite the district's strong Republican tilt. Greene, an arch-conservative, beat Harris by about 29 percentage points in 2024.

In the primary, Harris is facing Republican Clay Fuller, a Trump-endorsed former prosecutor who served in the Air National Guard.
