WASHINGTON (Reuters) - The White House on Friday decried as "out-and-out false" some of the criticism levelled against President George W. Bush at the Democratic convention, where Barack Obama was named the party's presidential nominee.

But White House spokeswoman Dana Perino insisted Bush had no plans to go on the attack against Obama when the Republican president addresses his own party's convention on Monday in St. Paul, Minnesota, where Sen. John McCain will be nominated.

Obama, in his acceptance speech in Denver on Thursday as the first black nominee of a major U.S. party, sought to link McCain directly to the unpopular president, saying their failed Republican policies were responsible for a faltering U.S. economy and a decline in America's standing in the world.

Other prominent speakers at the convention assailed Bush on everything from energy policy to the Iraq war.

"Some of the attacks are just out-and-out false -- for example, suggesting that the Bush administration hasn't invested in alternative or renewable energies," White House spokeswoman Dana Perino told reporters.

"This president has been unfairly attacked across the board by many Democrats for quite a while," she added.

Though Bush has sometimes returned fire, he has mostly avoided criticizing Obama by name during the campaign, and the White House signalled that the president would try to stay above the fray in his speech to his fellow Republicans.

Perino said Bush would use his nationally televised appearance to make the case that McCain is the "best qualified to be our next leader and commander in chief."
