President Donald Trump claimed Wednesday that the US election system is under "coordinated assault and siege," pledging to defend the country’s laws and Constitution.

Axar.az reports citing foreign media, in a pre-recorded video from the White House, which he called "the most important speech" he has ever made, the president said the Nov. 3 presidential election saw "lots of bad things” happen.

"We used to have what was called election day. Now we have election days, weeks, and months, and lots of bad things happened during this ridiculous period of time, especially when you have to prove almost nothing to exercise our greatest privilege, the right to vote," said Trump.

His remarks came a day after US Attorney General William Barr said there is no evidence of widespread voter fraud in the Nov. 3 presidential race that could change President-elect Joe Biden's victory.

Biden garnered 81 million votes, while his opponent received 74 million. The president-elect won 306 electoral votes and Trump has 232.

Trump said the constitutional process must be allowed to continue, adding he will ensure that every legal ballot is counted and that no illegal ballot is counted.
