ALLENTOWN (AP) - The mayor of Allentown never took a bribe or misused his office while running for U.S. Senate, his attorney said Thursday after a developer pleaded guilty to giving campaign contributions to the third-term Democrat in return for favorable treatment from the city.

Ramzi Haddad, 45, of Bethlehem, pleaded guilty to a federal bribery conspiracy charge, admitting that he raised tens of thousands of dollars for Ed Pawlowski's Senate bid after the candidate "made clear" to city vendors, including Haddad, that giving campaign cash "was a necessary condition for receiving certain favorable treatment from the city of Allentown," according to court documents released Thursday.Pawlowski has not been charged. His attorney, Mark Schamel, said in a statement that Haddad "received nothing from Mayor Pawlowski in exchange for legal campaign contributions.""Mayor Pawlowski has never accepted an improper payment, engaged in pay to play, or even been offered, let alone accepted a bribe," Schamel said. "Mayor Pawlowski is a trusted public servant who has never misused his office."Pawlowski suspended his Senate candidacy in July, days after the FBI raided Allentown City Hall.The court documents released Thursday did not identify Pawlowski by name but said the Allentown elected official who demanded campaign contributions from Haddad announced his Senate candidacy on April 17. That's when Pawlowski entered the race.Haddad said he agreed to raise $25,000 in campaign contributions for Pawlowski, but he told the mayor he needed him to intervene in the municipal inspection of one of his buildings. The official agreed to "get on" a particular inspector, and urged Haddad to "let me know" of any problems, court documents said.Haddad faces a maximum of five years in prison when he is sentenced on Dec. 18.The quid pro quo wasn't limited to Haddad, according to prosecutors. Pawlowski allegedly ordered city staff to do favors for other donors to his Senate campaign.The official tried concealing the plot by limiting his interactions with Haddad and other city vendors, destroying records, ordering government offices to be searched for electronic surveillance devices and using prepaid cellphones "that he believed would be difficult for law enforcement to monitor," court documents said.
