Washington: Congress is set to take up the reauthorization of a divisive program that lets U.S. spy agencies pore over foreigners' calls, texts and emails, with supporters like President Donald Trump saying it has saved lives while critics point to long-standing concerns about warrantless surveillance of Americans.A key provision of the Foreign Intelligence Surveillance Act permits the CIA, National Security Agency, FBI and other agencies to collect and analyze vast amounts of overseas communications without a warrant. It incidentally sweeps up the conversations of any Americans who interact with those foreigners targeted for surveillance.The program expires Monday, and critics want changes, including a requirement for warrants before authorities can access the emails, phone calls or text messages of Americans. They also want limits on the government's use of internet data brokers, who sell large volumes of personal information gleaned online, offering the government what critics say amounts to an end-run around the Constitution.House Republican leaders hoped to advance the legislation on Wednesday, but an initial procedural step was delayed. Rank-and-file members have pushed back despite a pressure campaign that included a trip to the White House and direct involvement from CIA Director John Ratcliffe.The chances of significant changes, however, seem have dropped since Trump announced his support for the program's renewal, saying it had proved its worth in supplying information vital to recent U.S. actions in Venezuela and Iran."The fact is, whether you like FISA or not, it is extremely important to our military," Trump said on social media Tuesday.U.S. authorities say the program, known as Section 702 of the law, is essential to national security and has saved lives by uncovering terrorist plots. Critics question what they say is a dangerous infringement on civil liberties and privacy.In a Truth Social post, Trump said a different FISA provision was used to spy on his 2016 campaign but that he supported Section 702's renewal despite misgivings that political adversaries could use parts of the law against him in the future. He urged lawmakers to extend the foreign surveillance program for 18 more months.

Washington: U.S. President Donald Trump said ‌the war with Iran was close ​to over, telling the world to brace for an "amazing two days", as the Pakistan army chief, who is the main mediator, arrived in Tehran in a bid to prevent a renewed conflict.The diplomatic push came as U.S. and Iranian officials weighed a return to Pakistan for further talks after negotiations there ended on Sunday without a breakthrough.Pakistan's military confirmed Field Marshal Asim Munir had arrived in Tehran. A senior Iranian source told Reuters that Munir, who had mediated the last round of talks, was heading to Iran "to narrow gaps" between the two sides.Amazing two days ahead: Trump"I think you're going to be watching an amazing two days ahead," Trump told ABC News reporter Jonathan Karl, according to a post by the reporter on X, adding he did not think it would be necessary ⁠to extend a two-week ceasefire that expires next week."I think it's close to over, yeah. I mean I view it as very close to over," Trump said in an interview on Fox Business Network conducted Tuesday and broadcast Wednesday. "We'll see what happens. I think they want to make a deal very badly."Talks to resume?Officials from Pakistan, Iran and Gulf states also said both sides could return to Islamabad in coming days.The talks last weekend broke down without an agreement to end the war, which Trump launched alongside Israel on February 28, triggering Iranian attacks on ‌Iran's Gulf neighbours and reigniting a conflict between Israel and Iran-backed Hezbollah in Lebanon.Trump's optimism lifted global stocks towards record highs. Oil prices - having fallen on Tuesday and in early Wednesday trade - were slightly up at around $95 per barrel, after the U.S. said its blockade of Iranian ports had halted seaborne trade in and out of Iran.Tankers interceptedThe U.S. military said it was turning back more vessels, including the U.S.-sanctioned, Chinese-owned tanker Rich ‌Starry which was seen heading back through the Strait of Hormuz on Wednesday.A U.S. destroyer stopped two oil tankers attempting to leave the ‌Iranian port of Chabahar on the Gulf of Oman on Tuesday, a U.S. official said.An Iranian supertanker subject to U.S. sanctions crossed the strait towards Iran's Imam Khomeini port despite the ‌blockade, Iran's Fars News agency said on Wednesday. Fars did not identify the ‌tanker or give further details of its voyage.While Iran and the United States appear so far to have avoided a major confrontation at sea since the United States began its blockade on Monday, Tehran has said it would retaliate against military action.Iran warningIran's joint military command ​warned it would halt trade flows in the ‌Gulf, the Sea of Oman and the Red Sea - which connects ​to the Suez Canal - if the U.S. blockade continued.Trump has also threatened to ⁠escalate if the war resumes. He told Fox Business Network: "...We could take out every one of their bridges in one hour. We could take out every one of their power plants, electric power plants, in one hour. We don't want to do that...so we'll see what happens."Return to IslamabadTrump told the New York Post on Tuesday that his negotiators were likely to return to Pakistan, thanks largely to ​the "great job" army chief Munir was doing to moderate ⁠the talks.Speaking later at an event in Georgia, Vice ⁠President JD Vance, who led the U.S. delegation at last weekend's talks, said Trump wanted to make a "grand bargain" with Iran but there was a lot of mistrust between the two countries.Iran's nuclear ambitions were a key sticking point at last weekend's talks. The U.S. had proposed a 20-year suspension of all nuclear activity by Iran - an apparent concession from longstanding demands for a permanent ban - while Tehran ⁠had suggested a halt of 3 to 5 years, according to people familiar with the proposals.The head of the International Atomic Energy Agency, Rafael Grossi, said the length of any moratorium on Iranian uranium enrichment was a political decision and suggested Iran might accept a compromise as a confidence-building measure.Washington has also pressed for any enriched nuclear material to be removed from Iran, while Tehran has demanded that international sanctions against it be lifted.Back-channel talksOne source involved in the talks said back-channel talks had made progress in narrowing gaps, bringing the two sides closer to a deal that could be put forward at a new round of talks.Complicating peace efforts, Israel has continued to attack Lebanon as it targets Iran-backed Hezbollah. Israel and the U.S. say ‌that campaign is not covered by the ceasefire, while Iran insists it is.Israel's security cabinet will convene late on Wednesday to discuss a possible Lebanon ceasefire, a senior Israeli official told Reuters, after Israeli and Lebanese officials held rare talks in Washington ​a day earlier.
