"Former Pennsylvania senator Arlen Specter said Thursday that Rick Santorum got his facts wrong..."

"... when he said that he endorsed Specter only after securing a promise that Specter would support GOP Supreme Court nominees."

Santorum, last night:

"I said will you support the president's nominees? We had a 51-to-49 majority in the Senate. He said, 'I'll support the president's nominees as chairman.'"

Specter, today:

"He is not correct. I made no commitment to him about supporting judges... I made no deal."
