WASHINGTON (AP) — Enrollment for the president’s health care law has grown to 7.5 million Americans, the Obama administration announced Thursday, handing President Barack Obama and the Democrats bigger coverage numbers to tout in the face of election-year attacks.

Sign-ups for the law stood at 7.1 million last week, but people who had started signing up when the enrollment period closed March 31, or who had trouble signing up, were given extra time to finalize their applications. Four hundred thousand more have now done so, Health and Human Services Secretary Kathleen Sebelius said in testimony before the Senate Finance Committee. Sebelius said she expects the figure to continue to grow.
