AFIACT Tether doesn't even aspire to any fixed time frame for redemptions, so it's even easier than a typical money market scenario. If all their assets were 30 day treasuries or shorter you don't even need to sell them - just wait the 30 days and then pay people then. Though I expect that even at tether's scale, markets for short term treasuries are liquid enough.
