I wasn't able to retrieve the actual article content — the page returned an "access denied" error (likely a JavaScript/bot-detection block), not the story text. I only have the headline to go on, which isn't enough to write an accurate, non-speculative summary.

From the title alone: Senator Chris Van Hollen reportedly accused President Trump of a "bait and switch" on Saudi Arabia, tying US-Saudi relations to a nuclear deal condition. But I don't have the details (context, what he actually said, timing, related developments) needed to summarise this responsibly.

If you can paste the article text directly, or provide an alternative link (e.g. a syndicated version), I can produce the full summary in the requested format.
