Rep. Adam Kinzinger (R-Ill.) is predicting "massive" retaliation from the Trump administration if Syria uses chemical weapons.
"We have to maintain that using chemical weapons will cost you far more than any gain you'll get," Kinzinger, a member of the House Foreign Affairs Committee, told the Washington Examiner.
"I think if they're used again, frankly it's gonna be a much more massive campaign."
His comments come after White House press secretary Sean Spicer said in a statement Monday that the U.S. had “identified potential preparations for another chemical weapons attack by the Assad regime” in Syria.
“As we have previously stated, the United States is in Syria to eliminate the Islamic State of Iraq and Syria. If, however, Mr. Assad conducts another mass murder attack using chemical weapons, he and his military will pay a heavy price,” Spicer added.
U.S. warships launched 59 cruise missiles at a Syrian airbase in early April in response to a chemical attack believed to be carried out by forces loyal to Syrian President Bashar Assad.
Kinzinger in the Examiner interview also pushed back against comments from Kremlin spokesman Dmitry Peskov, who earlier this week called the White House warning "unacceptable."
"We consider unacceptable any such threats to the legitimate government of the Syrian Arab Republic," Peskov said. "We strongly disagree with the wording ‘another attack,' because, as you know, despite all the demands of the Russian side, there was no independent international investigation of the previous tragedy with the use of chemical weapons."
Kinzinger said on Wednesday, however, that "we know that the regime used chemical weapons."
"No sane person would doubt that. Some crazy people might," he told the Examiner. "And [Russian President] Vladimir Putin and his infrastructure of course might deny that because it would do them no good to admit they were complicit in the least."
