Trump, who has not said whether he will run for president again after his defeat by Democrat Joe Biden in the 2020 election, was speaking at a rally in Conroe, Texas.

“Another thing we’ll do, and so many people have been asking me about it, if I run and if I win, we will treat those people from Jan 6 fairly,” Trump said to applause.

“We will treat them fairly. And if it requires pardons we will give them pardons. Because they are being treated so unfairly.”

Thousands of Trump supporters stormed the Capitol on Jan 6, 2021, the worst assault on Congress since the war of 1812.

Fuelled by Trump’s false claims that his November 2020 election defeat was the result of fraud, the attackers sought to stop Congress from certifying Biden’s victory.

One police officer who responded to the scene died the day after the attack, while four others who guarded the Capitol died later by suicide.

About 140 police officers were injured during the hours-long attack. Four rioters also died. More than 700 people have been charged with joining in the assault.
