Wisconsin Sen. Johnson says he, Trump are 'change agents'

(AP) — Republican Wisconsin Sen. Ron Johnson said both he and Donald Trump are change agents, defended himself from charges that he's in the pocket of special interests by saying "I am the working man" and accused the signature campaign finance reform championed by his challenger Russ Feingold as a "spectacular failure" in a debate Tuesday.

Johnson and Feingold sat side by side in the spirited and sometimes contentious debate in Milwaukee, the second and final face-off that comes three weeks before the election.

Johnson and Feingold disagreed on a bevy of issues, from their support of their party's presidential nominees, the Affordable Care Act, free trade, the minimum wage, immigration enforcement and reform and whose interests they would back in the Senate.

Johnson said voters were looking for dramatic change and both he and Trump are on the right side of the biggest issues, like how to fight terrorism and the importance of nominating conservatives to the Supreme Court.

Feingold is known for the law designed to cut back on the influence of special interest money in politics he co-wrote with Arizona Sen. John McCain, large portions of which were struck down by the landmark Citizens United Supreme Court ruling.
