In the U.S. presidential campaign, the major candidates traded fire today over welfare and health care. Republican Mitt Romney stepped up his accusations that President Obama has weakened welfare reforms.
Romney spoke at a rally in Des Moines, Iowa.
MITT ROMNEY (R): With a very careful executive action, he removed the requirement of work from welfare. It is wrong to make any change that would make America more of a nation of government dependency. We must restore and I will restore work into welfare.
(CHEERING AND APPLAUSE)
The Obama campaign insisted again that the president simply granted states more flexibility to deal with welfare paperwork.
And, in Denver, the president addressed a largely female crowd and talked about what Romney's vow to repeal health care reform would mean.
PRESIDENT BARACK OBAMA: Mr. Romney is running as the candidate of conservative values.
There's nothing conservative about a government that prevents a woman from making her own health care decisions.
(CHEERING AND APPLAUSE)
He says he's the candidate of freedom, but freedom's the chance, the opportunity to determine for yourself the care that you need when you it.
The president is on a two-day campaign swing. Romney is set to begin a multistate bus tour on Friday.
