How do I make requests from higher level coworkers who just found out they are going to be laid off?

I work with another department on a monthly basis and have to follow up with them to get the information I need. Usually I have to ask them several times to get what I need it time, but they are higher level people than me, so I just use polite persistence to get what my department needs from them.

There are some follow up items I have checked in on several times over the past week and have been told that they will send me what I need that day, but it doesn't end up being sent.

Today I was going to follow up again, but found out that a lot of people on this team were just told they were going to be laid off, most likely including the contacts I work with.

I don't really want to follow up on the day this was announced. What would good timing be and the best way to approach this situation if the information I need from them is approaching past due?
