"Welp." There's a word. A better one would be "resign"

As in "I resign." 

From Politico -

Utah Gov. Spencer Cox said Monday that the state's Covid data team “screwed up” and that Utah has not yet hit the 70 percent goal for adult vaccinations, admitting the error just days after celebrating the milestone.

“Welp. We screwed up. Because of a reporting error we have not yet hit 70% on our adult vaccinations,” Cox, a Republican, posted on Twitter Monday. “I promised to admit our mistakes and hold us accountable. I hope you will forgive us — and know we have made changes to ensure it won’t happen again.”

What does he regret more?

The lie or having to 'fess up about it?
