Sen. Bill Cassidy, R-La., who cast the deciding vote that officially confirmed Todd Blanche as attorney general, said his decision was not black or white but a "gradation of gray."

"If you're looking for a black or white decision here, you're not going to find it. This is a gradation of gray. But what I'm told as regards to the anti-weaponization fund, if you put it in the context of the political environment, the judicial environment, the process you would have to go back through in order to reinstate that effectively is dead," Cassidy said on CBS "Face the Nation." "Now, John Cornyn, a former state attorney general in Texas, was comfortable with it. I'm not an attorney."

Cassidy was asked if he is confident that Blanche will uphold the U.S. Constitution with respect to the upcoming elections.

"Well, of course, there's always this existential anxiety," he said. "But I am as confident as you can be about the future you are. I cannot predict the future, and this is not a black or white decision. But I'm confident on that."
