they just wanted to (walk through the house) and make sure I wasn't a part of any hate groups."
Harrison said he invited the Secret Service agents into the house and they were "very cordial."
''We walked through the house and my wife and 2-year-old were in the house," Harrison said.
He said they interviewed him for about 30 minutes and then left, not finding any evidence Harrison was a threat to the president.
''I'm still in contact with a lawyer right now," Harrison said. "I don't know what I'm going to do."
Harrison said he feels his First Amendment rights were violated.
McCool said the officer who pulled over Harrison misinterpreted the sign.
''We had an officer that his interpretation of the sign was different than what was meant," McCool said. "You've got an officer who had a different thought on what the word 'abort' meant."
McCool said the sign basically meant Obama should be impeached and it was not a threat.
''(The officer) shouldn't have taken the sign," McCool said. "That was (Harrison's) First Amendment right to voice his concern."
McCool said although the sign should not have been confiscated, the situation was made right in the end.
''We always try to do the right thing and in the end we believe we did the right thing by returning the sign," McCool said.
