For the second time in less than 24 hours, Joe Biden had to urge the US to unite against violence and division between political opponents.
We must unite as a nation, we must show who we are, he said on Sunday at the White House.
In the short speech, which was over in a few minutes, he repeated his dismay over the assassination attempt on Donald Trump.
This is not America. We cannot allow this to happen, he said.
Nothing is more important right now than that we stand united.
The President said that the federal police, FBI, had not yet been able to determine a motive and he urged caution against spreading rumors and not to draw hasty conclusions about the deed and what may have been behind it.
Let the FBI do its job, was the message from Biden, who said he had instructed the police to work "quickly and efficiently".
Joe Biden will hold a new speech at 2 am on Monday, Swedish time, from the Oval Office in the White House.
