I mean, the potential impact of corona virus was in the news well before February 13.
If you had been keeping an eye on this story that was pretty big, internationally, between early january and mid february, you didn't have to be Jim Cramer to know that it could have dramatic effects on the market if it got out of control. I'm not sure what information these members of congress had access to that the general public didn't that would have made any serious difference.
I think the more important question is: if these people knew this was coming (or the odds of it coming were significant enough to act financially on it), why wasn't anyone ringing the appropriate alarm bells or taking the appropriate action in congress?
