The former GOP presidential candidate told CNBC's "Squawk on the Street" that she disputes the characterization of Garland as a centrist.
"Of the three names that were floated, President Obama, in typical fashion, has chosen the most liberal out of those three," Fiorina said on Wednesday, adding that she thinks Obama is "seeking a fight" and "thumbing his nose at the entire Republican Party."
Ahead of Garland's nomination, Ed Rogers, former Reagan-Bush advisor and GOP political consultant, said that it is unlikely that any judge nominated by Obama would get a vote.
"There's no chance that this judge, no matter what his record might be or how distinguished his service has been, that he's going to get a vote," Rogers said. "It's just not going to happen."
