U.S. Democratic senators have criticized President Bush's proposal to revamp Social Security, on the eve of the retirement program's 70th anniversary.

Senator John Kerry, the 2004 democratic presidential candidate, said in a radio address delivered in Spanish Saturday that the president's proposal to add private investments accounts to the program will hurt Hispanics.

Democratic Senator Ken Salazar, from Colorado said in a separate English-language radio address Saturday the president is fabricating a crisis in the retirement program so he can push through his proposals to change it.

President Bush says his plans will help the program avoid severe funding shortfalls over the next few decades. A key part of his proposal is to allow younger workers to privately invest some of their Social Security funds which are now managed by the government.
