US Defense Secretary Pete Hegseth was met with a new round of questions from Congress on Tuesday, including fielding concerns from some Republican lawmakers who are starting to feel uneasy about how long the conflict has been going on without approval from the legislature.

When asked if there was truth to the reports that the US military is quickly burning through its munitions stores, he responded that "the munitions issue has been foolishly and unhelpfully overstated...we know exactly what we have, we have plenty of what we need."

Asked if there was a "Plan B" in place if Washington did not get what it wanted out of the conflict, Hegseth said: "We have a plan to escalate if necessary. We have a plan to retrograde if necessary. We have a plan to shift assets."

He did not provide any further details on these plans.
