President Barack Obama will speak again about health care reform Tuesday afternoon, offering brief remarks at the White House. After his comments, he will meet with Democratic members of the House Energy and Commerce Committee, which began marking up reform legislation Monday. As promised by White House aides, Obama has significantly ramped up his effort to secure passage of health care overhaul legislation, now either meeting with lawmakers or making public remarks — or both — on nearly a daily basis.The president is certain to spend a considerable amount of time on health care during a prime time press conference Wednesday and will travel to Cleveland on Thursday to again focus on the issue.
