HONOLULU – President Obama has enrolled in the federal health-care insurance exchanges, selecting a bronze-tiered insurance plan on the D.C. marketplace, the White House announced Monday.

In advance of Monday’s key enrollment deadline, Obama signed up for coverage over the weekend during the start of his holiday vacation here in Hawaii in what a White House official described as a “symbolic” act to promote the Affordable Care Act, his signature legislative achievement.
