"We take in sourcing from a variety of folks who are on the ground," she added. "I can't stipulate to one figure or another, it's very possible they're even higher than is being reported."
Leaf's remarks stood in stark contrast with those of President Joe Biden, who was
accused of "genocide denial" last month after he expressed "no confidence" in Palestinian health officials' Gaza casualty reports—figures deemed reliable by United Nations agencies, human rights groups, and Israeli and international media.
U.S. Secretary of State Antony Blinken—who heads an agency that has often
cited Gaza Health Ministry casualty figures—and other Biden administration officials have also cast aspersions upon Palestinian officials' reports, with National Security Council spokesperson John Kirby last month calling the ministry "just a front for Hamas."
The Gaza Health Ministry said Thursday that Israel's relentless asssault on Gaza by air, land, and sea has killed at least 10,812 people—including more than 4,400 children and 2,900 women—while wounding nearly 27,000 others and forcibly displacing around 70% of the strip's 2.3 million residents.
On Wednesday, Vedant Patel, the State Department's principal deputy spokesperson,
said during a press briefing that the U.S. government has "a rigorous process for evaluating whether something constitutes genocide, and we have not made that assessment in this case."
At least hundreds of jurists and other experts,
including one of Israel's leading Holocaust scholars, have accused Israeli forces of genocidal violence in Gaza.
Members of the women-led peace group CodePink confronted Leaf and Deputy Assistant Defense Secretary for the Middle East Dana Stroul during Wednesday's hearing.
When Leaf and Stroul responded affirmatively to House Foreign Affairs Committee Chair Michael McCaul's (R-Texas) question of whether Hamas committed genocide by killing over 1,400 Israeli civilians and soldiers during an October 7 surprise attack on Israel, one CodePink activist shouted, "What about Israel?"
CodePink's Leslie Angeline—who is currently on a hunger strike for a Gaza cease-fire—yelled out, "It's a genocide!"
"It's slaughter! It's genocide! It's ethnic cleansing! That's the truth," Angeline shouted as she was forcibly removed from the chamber by a U.S. Capitol Police officer and arrested.
"Call it what it is! Call it by its name," she added. "You're slaughtering Gazans!"
