WASHINGTON (CNN) - President Obama said Wednesday he was unable to guarantee that health care reform won't change how Americans get medical treatment, but he said any changes would be necessary and positive.
In a nationally televised news conference dominated by the health care issue, Obama delivered lengthy statements in response to Republican attacks on proposals he favors.
He also attempted to ease the concerns of people left confused by the fierce debate in Washington.
He repeatedly emphasized that the spiraling costs of the current system would bankrupt the nation while denying coverage to millions more Americans.
Asked directly if he could guarantee that an overhauled health care system won't change how people receive treatment, Obama said no.
"The whole point of this is to try to encourage what works," Obama said, addressing concerns that reform would take away the ability of people to choose their doctors and treatment.
