President Obama "has a deep-seated antipathy toward American values and traditions," former Sen. Rick Santorum (R-Pa.) alleged Thursday.

On the basis of Obama's actions last week in Europe and the president's nomination of Yale Law School Dean Harold Koh to be the State Dept.'s top lawyer, Santorum said Obama "disdains" U.S. values.

"Watching President Obama apologize last week for America's arrogance -- before a French audience that owes its freedom to the sacrifices of Americans -- helped convince me that he has a deep-seated antipathy toward American values and traditions," Santorum wrote in a piece for the Philadelphia Inquirer. "His nomination of former Yale Law School Dean Harold Koh to be the State Department's top lawyer constitutes further evidence of his disdain for American values."

Santorum ripped into Obama's nomination of Koh, whose nomination many conservatives have vigorously targeted.

Santorum wrote:
Koh tops the list of Obama's potential Supreme Court nominees. Is this what Sen. John Kerry meant when he once suggested that American policy must pass a "global test"?
