Unemployment benefits for millions of Americans struggling to make ends meet lapsed overnight as President Donald Trump refused to sign an end-of-year COVID-19 relief and spending bill that had been considered a done deal before his objections.

The fate of the bipartisan package remained in limbo on Sunday as Trump continued to demand larger COVID-19 relief checks and complained about "pork" spending. Without the widespread funding provided by the massive measure, a government shutdown would occur when money runs out at 12.01 am on Tuesday.
