WASHINGTON (Reuters) - A Senate Republican leader on Thursday urged President Barack Obama to begin anew in an effort to draft a bipartisan overhaul of healthcare.

Speaking at the White House healthcare summit, Lamar Alexander said, "Let's start over," and urged the president not to try to jam his own measure through Congress and a Republican wall of opposition. "It's not appropriate," Alexander said.
