During a nearly hour-long White House news conference, Bush also dismissed a human rights group's criticism of America's treatment of detainees in the wars in Afghanistan and Iraq.

''I'm aware of the Amnesty International report and it's absurd - it's an absurd allegation,'' the president said of Amnesty Secretary-General Irene Khan's suggestion that the Guantanamo Bay prison in Cuba is ''the gulag of our times,'' a reference to the Soviet Union's prison camps for millions of political dissidents.

''It seemed to me they based some of their decisions on the word of - and the allegations - by people who were held in detention, people who hate America, people that had been trained in some instances to disassemble - that means not tell the truth,'' Bush said.

The president also sought to counter doubts about progress in Iraq, where more than 760 people have been killed since a new government was announced in April and 77 American service members died in May.

Bush said the fledgling Iraqi government is ''plenty capable of dealing with'' insurgents, whom he called ''a group of frustrated and desperate people who kill innocent life.''

''I'm pleased with the progress,'' Bush said. ''I am pleased that in less than a year's time, there's a democratically elected government in Iraq; there are thousands of Iraqi soldiers trained and better equipped to fight for their country; that our strategy is very clear in that we will work to get them ready to fight, and when they're ready, we'll come home.''

The president also accused Senate Democrats of stalling on his nomination of John Bolton to become United Nations ambassador and said his administration wouldn't turn over documents they've requested concerning Bolton.

''I view it as another stall tactic, another way to delay, another way to not allow Bolton to get an up or down vote,'' Bush said.

''Just give him a simple up or down vote.''

Bush spent most of the news conference avoiding the word ''stalled'' when it came to his major proposals - from Social Security to the Central American and Dominican Republic free trade agreement - that are meeting strong resistance in a Republican-controlled Congress.
