US Senator Raphael Warnock has blocked an effort to fast-track the passage of a sweeping Russia-Iran sanctions bill, Punchbowl News reported on Tuesday.

The revised legislation, championed by the late Senator Lindsey Graham, a prominent Russia hawk, would authorize President Donald Trump to impose tariffs of up to 100% on goods from countries that buy Russian oil, including China and India.

Warnock, a Democrat from Georgia, placed a hold on the bill despite voting last week to advance it.

“Supporting Ukraine does not mean giving this unhinged president new powers to raise the price of everything through tariffs,” he said in a statement shared by Punchbowl News congressional reporter Laura Weiss.

Democrats have long described Trump’s policy of imposing tariffs on most US trading partners as chaotic and damaging to the domestic economy.
