Transcript for Biden accuses Trump administration of obstructing transition
Next tonight, we turn to politics. 23 days until the inauguration and President-Elect Joe Biden is blasting the trump administration, calling its failure to cooperate fully on matters of national security quote nothing short of irresponsibility. President trump golfing in Florida today has finally signed that covid relief bill, caving on his hand for $2,000 direct stimulus payment. Here's ABC's Rachel Scott. Reporter: Tonight, President-Elect Joe Biden sounding the alarm, accusing the trump administration of obstructing the transition and putting national security at risk. We have encountered road blocks from the political leadership at the department of defense and the office of management and budget. It's nothing short, in my view, of irresponsibility. Reporter: The president is still fighting to overhe election, after trying to derail the covid relief package millions of Americans are counting on. It really is a disgrace. Reporter: For days, he refused to sign the bill his own treasury secretary negotiated. The delay meant people like Bess Sullivan in Seattle saw their unemployment benefits expire. She's been out of work since March. What a way to slap people at Christmas time. Rr: The president claimed the $600 in direct payments his team negotiated wasn't enough, saying he wanted to send out $2,000 checks. I understand he wants to be remembered for advocating for big checks, but the danger is he'll be remembered for chaos and misery and erratic behavior if he allows this to expire. Reporter: And in the end, trump backed down and got nothing. In fact, his fellow Republicans are the ones opposed to sending bigger checks to Americans. Tonight, Democrats in the house are voting to do just that, though it will be an uphill battle in the gop-controlled senate. Okay, Rachel Scott joins us now from Washington. And Rachel, the bottom line, when can Americans expect to see those $600 checks and who is going to get them? Reporter: Tom, Americans who make less than $75,000 can expect to receive those one-time checks of $600. But tonight, the trump administration is scrambling to get them out. Secretary of treasury Steve mnuchin wanted the direct payments in the mail before the new year, but all of that was thrown out of the window when the president waited six days to sign that bill. Tom? Rachel Scott for us tonight.
