Here's a transcript from an exchange with The Hill's Niall Stanage at a White House press conference on Tuesday:

Stanage: You said today, as you've said a number of times, about the importance of the laws of war being upheld. Israel has killed around 11,000 Palestinians. Around two thirds of those are women and children. The situation in the hospitals is dire. Israel has dropped an astronomical amount of ordnance in very built-up areas. Is Israel, in your view, abiding by the laws of war? And if it is, how do you come to that conclusion?
 
Sullivan: Well, as I said yesterday, I?—?Jake Sullivan, standing here?—?am not in a position to be judge and jury to make that determination. It's a legal determination. What I can do is state for you the clear policy of the Biden administration, which we have been unequivocal about from the beginning of this conflict. And that is that even though Hamas is using civilians as human shields, is burrowing into civilian areas with its rocket emplacements that they are continuing to launch every single day at civilian areas in Israel, that puts an added burden on the IDF but it does not lessen their responsibility to act in ways that separate terrorists from civilians and does everything in their power to protect civilian lives.
