In this committee, and obviously in this study, we're not talking about buy America writ large. We're talking about federal infrastructure projects for the most part. You listed a bunch of other things, like aerospace and all those critical things, but those won't necessarily be affected.
Do you have a feel for what percentage of the 2.2 million tonnes that we export goes to those federal infrastructure projects? In other words, what is really at risk in terms of that 2.2 million tonnes, if we're not successful in achieving an exemption?
