Among other things, the possibility of attacking Iran's nuclear energy program is being discussed - more harshly than in the twelve-day war against Israel in June - as well as places where ballistic missiles are stored, according to anonymous American officials who spoke to The New York Times.
However, a cyberattack or another form of attack against Iran's security apparatus, which uses deadly force against the protesters, is more likely, according to the sources.
An American attack, which is considered likely to provoke a "powerful retaliation" from Iran, is said to be at least several days away.
Diplomatic options are also being considered, the sources said. On Monday, White House spokeswoman Karoline Leavitt said that "diplomacy is always the president's first choice" - but that Trump is also keeping the door open for airstrikes.
On Tuesday, the president will be informed about the various options, The New York Times writes.
CBS News reports that Trump has already been briefed on several different military options against Iran. According to the network's sources in the Defense Department, the options include cyber and psychological operations as well as military.
