BLM demonstrators joined by other groups in NYC

Black Lives Matter protesters were joined by other groups in Manhattan, New York on Thursday night, as votes in the US election were still being counted across the nation. President Donald Trump had earlier sought to undermine confidence in the nation's election, making unsupported accusations from the White House about the integrity of the results in his race against Democrat Joe Biden.

Hours earlier, Biden offered reassurances that the counting could be trusted, projecting a more presidential appearance while urging patience from Americans.

The candidates' sharply contrasting postures intensified a national moment of uncertainty as the nation and the world waited to learn which man would collect the 270 electoral votes needed to capture the presidency. Trump pursued legal options with little success, working the phones and escalating efforts to sow doubt about the outcome of the race.
