warren's tax returns since 2008. she's released 11 years. buttigieg has released 12. she's talking about the pre2008 tax returns during the late 2000s when she was a professor and also doing legal work. she was doing some legal cases then. back in may her campaign released roughly 60 cases that said what the case names were and the clients she was representing. so we know that information just not how much she was paid for it. now, she was asked if she would play ball on this effectively, if buttigieg started opening his fund rairzers, would warren release the tax returns. it doesn't sound like she's willing to play ball. >>. >> reporter: will you release the tax returns from late thousands? >> this is about what's going on right now. he should open up his fundraisers. he should release who is bundling for him and be clear who is on his finance team. this is not about what happened 15 jeeyears ago.
