How many people in congress made the exact same bet on the exact same information, and for them it's "legal?"
People act like the pervasiveness of insider trading in Congress is an indisputable fact, when there have been only a few trades with suspicious timing, which is similar to what you would expect statistically from 535 wealthier people trading with no insider information. The only case where I feel like insider trading is likely was Richard Burr's sales before COVID.
