MADISON, Wis. (AP) -- Paul Ryan is invested in the future of Republican Mitt Romney's presidential campaign -- and not just because the Wisconsin congressman could wind up on the presumptive nominee's ticket.
A federal fundraising account associated with Ryan gave Romney's campaign $10,000 in late May, according to a recent report filed with campaign finance regulators.
The political action committee established by Ryan, known as the Prosperity PAC, made the dual $5,000 donations on May 29.
Ryan is a seven-term congressman from southern Wisconsin who heads the House Budget Committee in Washington. He is among the Republicans often mentioned as a potential vice presidential pick for Romney.
