Rick Santorum admitted his three-year-old daughter, Isabella, to the Children's Hospital of Philadelphia on Saturday, the campaign said in a statement.

JACKSONVILLE, Fla. -- Republican Rick Santorum is pausing his presidential campaign after admitting his 3-year-old daughter, Isabella Santorum, to the Children’s Hospital of Philadelphia late Saturday. The child suffers from a serious birth defect.

“Rick and his wife, Karen, are admitting their daughter, Bella, to Children's Hospital of Philadelphia this evening,” said Hogan Gidley, the former U.S. senator's communications director. “The campaign will cancel Rick's upcoming Sunday morning Florida campaign schedule.  However, Rick intends to return to Florida and resume the campaign schedule as soon as is possible.”

The crucial Florida primary is on Tuesday.

WEST PALM BEACH, Fla. – Atlanta businessman and former presidential candidate Herman Cain endorsed Newt Gingrich Saturday night at a West Palm Beach Country Republican gathering after two months of wavering on whether he would offer his support to a fellow candidate.

WEST PALM BEACH, Fla. – Atlanta businessman and former presidential candidate Herman Cain will endorse Newt Gingrich for the GOP nomination for president tonight at a West Palm Beach Country Republican gathering, sources have told National Journal.

Since he quit his own campaign for president in December under a cloud of sexual harrassment allegations, the former pizza company executive has wavered on whether he would offer his support to a fellow candidate.
 
Gingrich’s campaign can only hope that the support of the once-popular candidate will give a shot of life to his campaign, which is beginning to falter in Florida after a series of rough debates and nonstop attacks from rival Mitt Romney. But Cain’s support may have lost his luster after nearly two months out off the campaign trail.

PANAMA CITY, Fla. – Campaigning in Florida’s conservative Panhandle, Mitt Romney on Saturday trained his fire on President Obama’s military record, particularly the size of the U.S. armed forces compared with the past.

What we at The Hotline learned this week:

NBC has asked Mitt Romney's presidential campaign to remove all of the network's footage from a new television advertisement that is airing in Florida. That would be a challenging, considering almost all of the ad is the Jan. 21, 1997 opening of NBC Nightly News.

In his weekly address, President Obama on Saturday blasted Sen. Mike Lee, R-Utah, who this week threatened to block all pending nominations before the Senate.

Sen. Marco Rubio, R-Fla., blasted President Obama's economic policies in the weekly Republican address, calling his push for a so-called millionaires' tax "divisive rhetoric."
