WASHINGTON ( CNN ) -- U.S. Rep. Joe Wilson -- the South Carolina Republican who heckled President Obama during his speech to a joint session of Congress -- has raised at least $ 1 million in contributions , a campaign aide confirmed . Rep. Joe Wilson , R-South Carolina , shouts `` You lie ! '' during President Obama 's speech Wednesday night . News of that cash haul comes after Wilson directly asked in a Web video for campaign cash to fend off attacks from political opponents and said he 's standing by his opposition to Democratic efforts at health care reform . Wilson has come under fire for shouting `` you lie '' to Obama during the Wednesday night address to Congress on health care reform . The lawmaker soon apologized for his behavior , viewed by Republicans and Democrats as an ill-mannered breach of political decorum . The remark energized Wilson 's opponents and supporters , who have been opening their wallets and sending donations to Wilson and Rob Miller , his Democratic opponent in next year 's congressional race . Miller -- who has reported raking in more than $ 1 million as a result of the outburst -- ran against Wilson last year , losing by 8 percentage points . It was Wilson 's smallest margin of victory in his five elections to Congress . In an e-mail to supporters Friday night , Miller said he had raised the money in small contributions in less than 48 hours -- a total that dwarfs the $ 67,000 he has taken in during the entire first half of the year . Wilson shouted `` you lie '' after Obama laid out what the congressman said were `` bogus claims '' about health care reform `` spread by those whose only agenda is to kill reform at any cost . '' `` The best example is the claim made not just by radio and cable talk show hosts , but by prominent politicians , that we plan to set up panels of bureaucrats with the power to kill off senior citizens , '' Obama said in his speech . `` Now , such a charge would be laughable if it were n't so cynical and irresponsible . It is a lie , plain and simple . Watch CNN 's John King and Joe Johns talk about little words and big money » . `` There are also those who claim that our reform efforts would insure illegal immigrants . This , too , is false . The reforms I 'm proposing would not apply to those who are here illegally , '' Obama said . It was at that point Wilson made his now-infamous exclamation , sparking boos and Obama 's retort : `` It 's not true . '' In a YouTube video released on Thursday , Wilson said , `` On these issues , I will not be muzzled , I will speak up and speak loudly against this risky plan . '' He added : `` Supporters of the government takeover of health care , and the liberals who want to give health care to illegals , are using my opposition as an excuse to distract from the critical questions being raised about this poorly conceived plan . '' CNN 's Peter Hamby contributed to this report .
Money pours in after Rep. Rob Miller directly asks for funds in Web video . YouTube video : Wilson says he 's still in opposition to Dems ' health care plans . Wilson 's '08 rival , Rob Miller , earlier announced he had reached at least $ 1 million . Miller lost by five points in '08 , the closest of 8 races Wilson has faced .
