Congressional investigators are targeting videos the Bush administration has made to promote the new Medicare law. The videos were made to look like news reports -- and didn't disclose that they had been paid for by the government. The General Accounting Office says the administration violated a prohibition against using public money for propaganda. Democratic Senator Frank Lautenberg asked for the inquiry. Lautenberg says he's going to introduce legislation to force President Bush's re-election campaign to pay for the videos. Democratic presidential candidate John Kerry says the situation is another example of how the White House has "misrepresented its Medicare plan." A health department spokesman blames TV stations that he says "chose not to identify the source of the material."
