(CNN) - A key adviser to Mitt Romney's 2008 bid for the White House is returning to the fold, another sign that the former Massachusetts governor is building up to what appears to be another run for the Republican presidential nomination.
Romney's Free and Strong America PAC announced Monday that Lanhee Chen will join the political action committee as policy director. Chen served as Romney's chief domestic policy adviser during the 2008 campaign. Chen was also a health policy adviser to President George W. Bush's 2004 re-election campaign and served at the Department of Health and Human Services during the Bush administration.
Romney's PAC is also announcing that it's donating $25,000 to the New Jersey GOP to help the state party as it aids Republican candidates in legislative elections this year. Romney aides say that the donation brings to over $300,000 the amount of money Romney's PAC has contributed to congressional candidates and Republican party organizations this year.
"It is important to help candidates who are fighting for conservative principles, whether in Washington or in the states," Romney said in a statement
Romney also was a big supporter of Republican candidates last year during the midterm elections. Such assistance could pay dividends later this year and next year if Romney, as expected, runs again for the White House.
