Framing a new argument against President Barack Obama's healthcare law, congressional GOP leaders called Tuesday for a delay in the law's requirement that individual Americans carry health insurance. House Speaker John Boehner, R-Ohio, and other senior Republicans told Obama in a letter that his decision last week to grant a one-year delay for employers but leave in place provisions for individuals and families had created many new questions and concerns. At a Capitol Hill news conference, Boehner vowed to hold another vote this month to remove the individual mandate, arguing that it was necessary to "correct this injustice." "If businesses can get relief from Obamacare, the rest of America ought to be able to get relief as well," Boehner told reporters. He later added, "We'll have another vote, count on it."
