Hegseth posts video defending himself amid impeachment calls after Republicans' loss

US War Secretary Pete Hegseth, who's being blamed for Republicans' midterm poll loss, posted a video defending himself. Calling the impeachment calls a "sham", he said, "They attack us because we're effective...won't work against me...we'll not back down...we've only just begun to fight." Democrats have vowed to investigate Hegseth's handling of Pentagon, including his firing of senior generals.
