Biden spoke from the Oval Office in prime time

He cheered bipartisan debt deal he'll sign two days before 'X date' 

Biden vowed to pursue 'tax cheats,' said he will sign the deal into law Saturday

President Joe Biden delivered his first Oval Office address as president from behind the Resolute Desk to hold up a deal to avoid defaulting on the nation's debt as a substantial bipartisan achievement.

'We averted an economic crisis – an economic collapse,' Biden told the nation Friday night.

'Passing this budget agreement was critical,' Biden said, speaking in a low voice during the prime time broadcast. 'The stakes could not have been higher. If they had failed to reach an agreement on the budget, there were extreme voices threatening to take America for the first time in our 247 year history, in a default on our national debt.'
