I wasn't able to retrieve the article text — the page blocks automated access, and I don't currently have permission to use web search to find alternative coverage (the request for that tool was denied). I can only work from the headline and byline context, as with the previous attempt.

SUMMARY:
The Hill's live-updates page reports that Dr Anthony Fauci invoked his Fifth Amendment right against self-incrimination during a Senate hearing examining the origins of COVID-19. The headline indicates Senator Rand Paul, a long-standing critic of Fauci's role in pandemic-era policy and a proponent of the lab-leak theory, was involved in the exchange. Beyond this, the full article could not be retrieved, so the specific questions Fauci declined to answer and the committee's response cannot be confirmed.

The page also references the Trump administration and Iran, suggesting the live-updates format covered several unrelated news threads from the same day rather than a single story. Because the source page denies automated access and no alternative report could be checked, further detail on what was said, by whom, and the hearing's outcome cannot be verified at this time.
