WASHINGTON (CNN) - The chairman of the Republican Party of Pennsylvania Chairman said Tuesday that Arlen Specter owes Republican voters in the state an apology for saying in the past he would not switch parties.
"I, like many of my fellow Pennsylvania Republicans, took Senator Specter at his word when he said that he would not switch parties, and I believe he owes every Republican who has supported him over the last three decades an apology," said state GOP chairman Rob Gleason in a statement.
Gleason also said Specter should "do the right thing and proactively return any and all campaign contributions he has received in recent months to run as a Republican in the upcoming election."
Specter said in a statement earlier Tuesday that he planned to return donations if he was asked to do so. "Upon request, I will return campaign contributions contributed during this cycle," he said.
Saying he is "deeply disappointed" in Specter, Gleason made a point of stressing that "the Republican Party has room for conservatives and moderates because we are the party of ideas."
