(CNN) - The Republican representative from Missouri who landed in the headlines and drew heavy Republican criticism for controversial comments on rape he made in an interview last month launches a new campaign television ad Saturday.
The new spot by Rep. Todd Akin hammers the Democrat he hopes to unseat, Sen. Claire McCaskill, over her support of President Barack Obama's health care law.

Titled "Broken Trust," the ad uses a clip of McCaskill at one of the contentious town hall meetings held in the summer of 2009 when legislators returned to their states and held forums on the health reform law.
"You don't trust me?" McCaskill is seen asking a largely hostile crowd in the ad, as shouts of "No" can be heard.
The narrator reads, "McCaskill broke our trust when she cast the deciding vote to pass Obamacare, cut Medicare by almost a trillion dollars, and killed jobs with higher taxes, spending, and debt.
"McCaskill voted with Obama 98% of the time," the narrator continues, before audio of Obama endorsing McCaskill rolls.
The senator's own latest television ad, however, touts her status as a centrist.
"All senators are ranked, one to 100, liberal to conservative," she said. "You're looking at number 50."
McCaskill was also not the last senator to announce she would support the health law.
The Akin spot closes with McCaskill saying, "You've got every right, if I decided to run again, to do everything in your power to fire me."
A source familiar with the spot says it will air in every market in the state.
Erik Dorey, a spokesman for McCaskill, said in a statement responding to the ad, "Akin is trying once again to mislead voters about Claire's record because he knows his own beliefs are just too extreme for Missouri."
"Missouri families know exactly who they can trust to protect Medicare, Social Security and student loans, and it's not Todd Akin," Dorey said. "Claire's always been a Senator on our side, fighting to protect these safety nets. On the other hand, Todd Akin's been working to abolish the minimum wage and eliminate Social Security and Medicare, all while protecting tax giveaways for mega-millionaires and big oil at the expense of working families."
Attention turned to Akin the week before the Republican National Convention when the congressman said in an interview on a local television station that "doctors" had told him pregnancy is rarely a result of sexual assault. "If it's a legitimate rape, the female body has ways to try to shut that whole thing down," he said in an interview with KTVI.
Those comments led to high profile Republicans either encouraging him to back out of the race or vowing not to support his candidacy if he continued his challenge of McCaskill.
Days later, he released a television ad stating that "rape is an evil act" and apologizing for having "used the wrong words in the wrong way."
The race is seen as important to Republicans in winning a majority in the Senate.
Race ratings from two top independent election watchers differ slightly in their prediction of the November outcome. The Cook Political rates the race as a toss up, while the Rothenberg Political Report says it leans in McCaskill's favor.
