In the latest Fox News poll, Joe Biden widened his lead over US President Donald Trump to 12 points and Trump is not happy on what is normally his favorite news channel. 

The survey found the former US Vice President Joe Biden notching 50 percent in the latest polls, with Trump falling well behind with 38 percent. The difference in the May survey of Fox was 48 to 40 percent.

The US commander in chief ranted furiously Friday morning on Twitter, writing that Fox News is "out with another of their phony polls, done by the same group of haters that got it even more wrong in 2016... Fox is terrible," Joel Connelly of SeattlePI reported.

Those surveyed pointed to the ongoing global health crisis, unemployment and racism as the country's three key threats, with 64 percent, 67 percent, and 67 percent listing them as the "major" danger, respectively.

Around 60 percent did not approve of Trump's decisions on race relations, while 32 percent approved. By comparison, in May, 56 percent and 37 percent gave the same answers.

Although less than 20 percent stated they or anyone in their household had protested against the killing of George Floyd, who died after a white police officer knelt at his neck for almost nine minutes, some 57 percent supported the demonstrations, compared to 35 percent who disapproved.

The survey was carried out from Saturday to Tuesday by the Democratic group Beacon Research and the Shaw & Company Republican research department. Researchers made telephone interviews with 1,343 registered voters selected at random across the United States.

The survey reported a margin of plus-minus 2.5 percentage points sampling error for all registered electors. It is still early, and the Electoral College will decide on the presidential election itself, but the results have been consistent with other polls showing the Democratic nominee, Biden, with a big edge over Trump nationally.

A CNBC survey, released Wednesday, gave Biden a 51 to 41 percent lead, while a Quinnipiac University survey conducted on Thursday placed him up, 49-41 percent.

Trump has been lashing out as surveys clearly indicate he is falling behind by a wide margin to the presumptive Democratic presidential nominee in the past few weeks, going so far as to hire his own pollster and demand CNN to say sorry for one of its polls.

Last week, CNN responded to the demand from the US president's re-election campaign. CNN's general counsel described the letter as factually and legally without any basis.
