Actor Dennis Quaid lent his support on Capitol Hill to Democrats seeking to derail a plan to provide pharma companies immunity from lawsuits, according to the Baltimore Sun. Quaid's infants were involved in a high-profile medication mishap when they received an overdose of heparin, a blood thinner, at a Los Angeles hospital. The heparin had been mislabeled. The Supreme Court is expected to hear a case this fall that could exempt drug makers purveying FDA-approved drugs. Quaid's testimony took place at a House Committee hearing, according to the Baltimore Sun. The babies have recovered.
