The Republican Party of Pennsylvania launched a last-minute television ad that calls attention to Barack Obama's relationship with his controversial former pastor, the Rev. Jeremiah Wright, CNN reports.
The retired pastor's ties to Obama became an issue during the primary season after controversial clips of Wright's sermons were circulated and widely discussed on the Internet and on television.
Obama later condemned Wright's remarks and said he would have left his church if his pastor had not retired and had not acknowledged making comments that "deeply offended people."
Sen. John McCain has repeatedly said he does not believe Obama's relationship to Wright should be an issue - to the ire of some Republicans who feel it raises questions about the Illinois senator's judgment.
McCain's running mate, Gov. Sarah Palin, appeared to suggest last month that Wright is a fair issue to raise, but said ultimately it is McCain's decision.
