Some lawmakers on both sides of the aisle aren’t pleased with Mylan’s decision to reduce the cost of an EpiPen for some customers, saying the move does not go far enough.

Mylan announced on Thursday that it is using a savings card to reduce the price of the allergy treatment EpiPen by up to $300, or roughly half the cost of a pack of two. The move didn’t sit well with Rep. Elijah Cummings, D-Md., who had been calling for hearings on the price spike.
