They are planning to talk with lawmakers after days of suspicions expressed by USA officials that Iran was responsible for attacks last week on two Saudi oil-pumping stations and an earlier sabotage of four oil tankers.
In April, hardliners in the Trump administration pushed to label Iran's Islamic Revolutionary Guard Corps a terrorist organization, despite warnings that the move could endanger USA personnel in the Middle East.
The US resorted its sanctions on Iran previous year and extended them this month, ordering all countries to halt imports of Iranian oil or face sanctions of their own. Overall, 39% approve of Trump's policy.

On Tuesday, during an interview with CNN, the Iranian foreign minister stated the United States was "playing a very, very risky game" by strengthening its military presence in the region.

Tehran and Washington have escalated rhetoric against each other in recent weeks as the United States has tightened sanctions with what it says is the goal of pushing Iran to make concessions beyond the terms of its 2015 nuclear deal. Republicans also favoured the accord negotiated by the Democratic administration of President Barack Obama, with a little more than half saying they supported it.
Iran has allegedly sabotaged oil tankers off the coast of the United Arab Emirates and Yemen's Iranian-aligned Houthi rebels have carried out drone attacks on Saudi oil pumping stations amid USA intelligence warnings that Iran or Iran-backed groups could threaten U.S. interests.

Trump's moves have helped set the stage for the current increased tensions between the United States and Iran.
