U.S. lawmakers have voiced growing concern over the possibility of American ground forces being sent into Iran.

Democratic senators highlighted the risks posed by Russian and Chinese support for Tehran, raising alarms about national security and the human cost of the conflict.

Following a classified briefing from Trump administration officials to the Senate Armed Services Committee, Senator Jeanne Shaheen of New Hampshire said Democrats were alarmed by the administration's handling of the Iran war.

She told CNN, “We know that Russia is already helping with intel, providing that to Iran, and that there's an axis with Russia and China, Iran and North Korea that puts at greater risk the United States and our national security.”

Shaheen and other senators emphasized the need for public testimony from administration officials to clarify the potential costs, duration, and strategy of the conflict.

Intelligence on Russian support

Two sources familiar with U.S. intelligence reports indicated that Russia is supplying Iran with targeting intelligence on U.S. bases and ships.

Senator Richard Blumenthal of Connecticut warned, “We seem to be on a path toward deploying American troops on the ground in Iran to accomplish any of the potential objectives here.”

Blumenthal highlighted the heightened risks due to Russian and Chinese involvement: “Literally, Russia seems to be aiding our enemy actively and intensively with intelligence and perhaps with other means, and China also may be assisting Iran.”

Lawmakers seek transparency

Both Shaheen and Blumenthal stressed that the American public deserves more information about:

The potential cost of the war
The danger to U.S. military personnel
The risk of escalation and widening conflict

They criticized the administration for leaving many questions unanswered after a series of closed-door briefings.

The lawmakers’ statements coincided with reports that the White House may request additional funding for the Iran conflict.

Several congressional aides suggested that President Donald Trump could seek around $50 billion, although some officials believe the request may ultimately be higher.
