Paul's comments came during a speech about 'blowback' due to U.S. intervention in the Middle East.

"What's happening in the Middle East, in particular with Gaza right now, we have some moral responsibility for both sides in a way because we provide help and funding for both Arab nations and Israel," Paul said.

"We have a moral responsibility, especially now today the weapons being used to kill so many Palestinians are American weapons and American funds are being used for this," he added.

"But there's a political liability, which I think is something we fail to look at because too often there's so much blowback from our intervention in areas that we shouldn't be involved in," he continued.
