Mark Isakowitz, chief of staff to Ohio Republican Senator Rob Portman has joined Google as VP-government affairs & public policy in Washington.

He replaces former Staten Island/Brooklyn Republican Congresswoman Susan Molinari.

Google advertising and search procedures are under intense scrutiny in DC. President Trump also has accused the company of being biased against conservative media outlets.

“Mark brings more than 30 years of experience in Washington, serious policy knowledge, and an impressive record of bridging divides and achieving results,” Karan Bhatia, Google’s government affairs chief, said in a statement. "He will help Google work with lawmakers to support policies that encourage growth and responsible innovation."

Isakowitz served as Portman’s COS for five years and earlier was president of Fierce Isakowitz & Blalock lobbying firm.
