Sen. Elizabeth Warren is demanding answers to economic questions surrounding the Iran war, ticking off a list of queries about the impact on food, energy and retail costs, among other concerns, in a letter sent Friday to administration officials.

The liberal Democratic firebrand from Massachusetts ripped President Donald Trump, whom she said has “dragged the United States into an illegal and reckless war” that will hurt U.S. consumers, particularly in the middle and lower classes.

“I write today with grave concern that President Trump is weakening an already fragile economy, and will continue to do so, pouring billions of dollars into a war that will drive up prices, slow growth, and leave American families with higher costs while they are forced to foot the bill,” Warren said, according to a letter exclusively obtained by CNBC.

Warren is the ranking member on the Senate Banking, Housing and Urban Affairs Committee.

Since the war began three weeks ago, energy costs have soared. The benchmark global oil price is approaching $110 a barrel, with costs at the pump nearing $4 a gallon, or about $1 higher than a month ago, according to AAA.
