Both my own fetch attempt and the article text you supplied were blocked by The Hill's site (403 Forbidden / JavaScript-required access page) — I have no actual article content to work from, only an access-denied message.
I can't produce a reliable summary without the real text. If you're able to copy and paste the article body directly from the page (or another source that carries the same story), I'll summarise it right away.
