Four weeks into the ceasefire that has largely halted fighting in Iran, the U.S. and Iran remain locked in a standoff over the Strait of Hormuz, through which a fifth of the world’s traded oil and gas passes in peacetime.

Conservative and liberal justices on Wednesday questioned whether Trump’s order declaring that children born to parents who are in the United States illegally or temporarily are not American citizens comports with either the Constitution or federal law.

The U.S. and Israel launched the war Saturday, targeting Iran’s leadership, missile arsenal and nuclear program while suggesting that toppling the government is a goal. But the exact aims and timelines have repeatedly shifted, signaling an open-ended conflict.

The remarks by two Iranian officials come as America has assembled its biggest deployment of aircraft and warships to the Middle East in decades. The buildup is part of President Donald Trump’s efforts to get a deal to constrain Iran’s nuclear program while the country struggles at home following nationwide protests.

The president said he was asking for territory that was “cold and poorly located" and that the U.S. had effectively saved Europe during World War II while declaring of NATO: “It’s a very small ask compared to what we have given them for many, many decades.”

Seemingly contradictory statements from Trump and Secretary of State Marco Rubio have suggested at once that the U.S. now controls the levers of Venezuelan power or that the U.S. has no intention of assuming day-to-day governance and will allow Maduro’s subordinates to remain in leadership positions for now.

President Donald Trump’s executive order to end birthright citizenship for the children of people who are in the U.S. illegally has been halted nationwide by three district courts around the country. Appeals courts have declined to disturb those rulings.
