Pentagon chief Pete Hegseth joined CBS's Margaret Brennan on Sunday for an interview which quickly degenerated into a tense, finger-pointing segment over billions poured into the military-industrial complex, as well as foreign coffers, amid multiple global hotspots and a couple major war fronts - most notably Ukraine and the Middle East.Brennan pressed Hegseth on the hollowed-out state of American arms stockpiles, invoking a recent plea from Ukraine for localized weapon production. "Let me ask you before you go about what is going on with US munitions and stockpiles here," Brennan posed. "Ukraine's President Zelensky was on this program a few weeks ago. He made a plea not just for more interceptors, but for the ability to produce them, for friendly governments to be able to produce patriots. Some Republican lawmakers support this idea. Do you?"Hegseth pivoted immediately to 'everything is fine' talking points regarding American stockpiles... "Nobody makes better and more munitions than the United States of America, and we are open to co-production wherever we can,” Hegseth said. "And because of this administration, we're supercharging our arsenal of freedom, building more, building faster, opening up the Pentagon, ripping through the Pentagon bureaucracy to force industry to move faster. So our stockpiles are strong, and it will only get stronger in the future." Watch the tense and very testy exchange unfold below:Hegseth: Nobody makes better or more munitions than the US.
