Tehran vowed to respond after reports that the USS Spruance fired on and seized an Iranian-flagged cargo vessel accused of attempting to run a Strait of Hormuz blockade, escalating already high tensions in the region.
Here are the key US political developments from Sunday, April 19.

US benchmark oil contract West Texas Intermediate (WTI) surged late Sunday after Iran accused the United States of violating a ceasefire that has been in place since early April.
WTI crude rose 7.5% to $90.17 per barrel by 8pm ET, while Brent North Sea crude gained 6.5% to $96.27 per barrel.
Iran’s military vowed retaliation after reports that the USS Spruance fired on an Iranian-flagged cargo vessel in the Gulf of Oman, which allegedly attempted to breach a US naval blockade. The Strait of Hormuz—an essential route for global oil and liquefied natural gas—has been largely disrupted since the start of the US-Israel conflict with Iran.
Separately, former US President Donald Trump said the US military had taken control of an Iranian-flagged container ship that tried to pass through the blockade near the Strait of Hormuz.
Tehran has no current plans to take part in new negotiations with the United States, Iranian state media reported on Sunday evening, just hours after Donald Trump said he was sending negotiators to Islamabad.
Energy prices
US Energy Secretary Chris Wright said gas prices may not fall back below $3 per gallon until 2027, noting that while it could happen as early as this year, it is also possible consumers may have to wait until next year or beyond.
Politics and religion
Republican Senator John Kennedy of Louisiana criticised Donald Trump’s recent comments about Pope Leo during a Fox News interview, saying he disagreed with what he called the president’s “new holy war” with the pontiff, while still expressing support for Trump overall.
Pope Leo XIV, meanwhile, said on Saturday that he was not interested in debating Trump over the Iran conflict, but would continue promoting a message of peace through the Church.
Analysis
Analysts say Trump’s decision to send US officials to Islamabad for talks with Iran, shortly after renewed tensions around the Strait of Hormuz, signals that the waterway remains a key bargaining chip in ongoing geopolitical negotiations.
