On this week’s Fox News Sunday, Wallace was all over Miller, challenging him to provide some explanation for how Trump’s national emergency is a national emergency, when Trump himself essentially admitted it wasn’t a national emergency. And when Miller tried to fend off the questions with talking points, Wallace peppered him with followups.

But Miller had an especially tough time getting around one line of questioning.

Wallace began by schooling Miller on the U.S. Constitution, telling him “I know that you are a constitutional conservative, and you believe that the constitution should be interpreted as written,” then proceeding to read to him from the Constitution. “Article 1 section 9 clause 7 of The Constitution, as written, ‘No money shall be drawn from the treasury, but in consequence of appropriations made by law,'” he read.

“Isn’t what President Trump want to do a clear violation of what the founders, what James Madison talked about, was giving Congress the power of the purse?” Wallace asked.

Miller countered by citing the National Emergencies Act, which actually doesn’t overrule the constitution. Wallace interrupted him.

“But let’s talk about national emergency, national emergencies have been declared 59 times since 1976 when the law was passed, the National Emergencies Act,” Wallace said. “Can you point to a single instance, even one, where the president asked Congress for money, Congress refused to give him that money, and the president then invoked national emergency powers to get the money?”

Miller tried to dodge the question again, telling Wallace “These authorities’ specifically refers to the use of military construction funds. Other emergencies, for example, were declared…”

“Wait,” Wallace said, cutting Miller off again. “If you want to talk about military military constructions, do you know how many times military construction has been invoked as a National emergency? Twice. Twice. Once by George H.W. Bush during the middle of the Gulf War, and the second time by George W. Bush right after 9/11. This is hardly comparable to either of those.”

Miller tried to change the subject again by asking Wallace an unrelated question, but Wallace was not having it.

“You know, the joy of this is I get to ask you questions, you don’t get to ask me,” Wallace said, and added “Answer my question. Can you name one case where a president has asked Congress for money, Congress has refused, and the president has then invoked national powers to get the money anyway?”

After one more shot at dodging the question, Wallace concluded “So the answer is no, there hasn’t been a single case like this.”
