Obama told Brown he looked forward to working with him on economic issues, said White House press secretary Robert Gibbs.
Gibbs said Obama also telephoned the Democratic loser, Martha Coakley, and thanked her for advocating "on behalf of working people." She quoted the president as saying, "We can't win them all."
Brown's victory will make it much harder, if not impossible, to pass Obama's health care overhaul bill in Congress.
