MILWAUKEE (WITI) -- FOX6 News has learned Milwaukee Mayor Tom Barrett will spend a second night in the hospital. Mayor Barrett was hospitalized Sunday, December 8th after participating in a 20-kilometer run at the Pettit Ice Center.
Sunday was Mayor Barrett's 60th birthday.
Mayor Barrett's spokesman says the Mayor had planned to run 60 minutes on his birthday, but it snowed, so the Mayor headed over to the Pettit Center to run. The Pettit Center was closed to the public for the Badgerland Striders 20K run -- and the Mayor decided to sign up.
He was treated for exhaustion following the race.
"I was surprised to hear it because I just remarked to the Mayor last week that I thought he was looking even in better shape and it was obvious he was working out, so I was a little bit surprised," Alderman Tony Zielinski said.
On Monday, Mayor Barrett underwent a series of tests at the Wheaton Franciscan Heart Hospital of Wisconsin. A statement from Mayor Barrett's spokesman says nothing alarming was found -- but doctors recommended Mayor Barrett stay one additional day at the hospital.
A statement from Mayor Barrett's spokesman says the Mayor has spoken twice by telephone to his staff at City Hall on Monday.
While scheduled meetings on the Mayor's calendar have been postponed, his spokesman says he continues to monitor city business from the hospital.
A message on Mayor Barrett's Facebook page Monday afternoon said: "Tom is thankful for all your good wishes and is looking forward to being back in the office very soon."
