That was not "giggling."
"Giggling" is what little kids do when you tickle them. The word, by itself, has mostly positive connotations.
What Granhold was doing was "guffawing." She might just as well have combined it with some "knee-slapping."
When VP Harris does it, it's most-aptly described as "insane tittering," like what a knife-wielding psycho might emit.
But back to Granholm: Her laughter was inappropriate mostly because it indicated that she had (insincerely) interpreted the question as meaning, "What will you, Madam Sec'ty, do to solve America's energy problem overnight?"
What the reporter was actually asking was, "Is there anything that the Biden Administration plans on doing to address this serious problem?!"
(The obvious response would, of course, have been: "Yes, we could simply undo all of Biden's meddling and return to Trump's energy agenda!")

SHOW ME, "GUFFAW . . "
