A House Democratic aide speculated to TPM that, for procedural reasons, House Republicans could not use their “calendar day” trick again. After voting down Meeks’ proposal, Republicans moved to block any further challenges to Trump’s tariffs until March 2026. By that point, the Supreme Court will likely have ruled on whether the president can continue using emergency powers in this way. The lion’s share of Trump’s tariffs have been levied under authority that he has asserted himself to have under the International Emergency Economic Powers Act, or IEEPA. On Tuesday, he voted to block his own ability to challenge Trump’s tariffs.
