You can see that she literally doesn’t give a shit.

They want to give long speeches of rehearsed lines in order to make it sound as if their actions are not illegal or wrong. It's an old overused tactic, sometimes it's partisan, others like Bill Barr and his childish semantics a cover-up.

They're also trying to burn up her time so she can't ask more questions. You notice she asked the chair to reclaim her time.

The problem is, people aren't buying it, and they've seen it already too many times. It's just like when Trump sycophants tried to attack Waltz military record, no one cared, it's just not 2004, Waltz served and he didn't have to, and Viet Nam ended 50 years ago.
