U.S. President Donald Trump injected confusion into the outlook for COVID-19 relief on Tuesday night, demanding changes to the bipartisan legislation approved by Congress less than 24 hours earlier.

In a surprise video announcement posted on his Twitter account, Trump called the bill a "disgrace” and said it was full of "wasteful and unnecessary” items. He demanded that lawmakers increase the stimulus checks due to go out to most Americans from the "ridiculously low” amount of $600 to $2,000 — or $4,000 for a couple.

"I am asking Congress to amend this bill,” Trump said. "Send me a suitable bill or else the next administration will have to deliver a Covid relief package. And maybe that administration will be me, and we will get it done.”
