In his first sit-down news interview since winning a second presidency in November’s election, Donald Trump renewed promises to pardon his supporters involved in the attack on the US Capitol in early 2021.

He also doubled down on promises of mass deportations and tariffs in the conversation with NBC’s Meet the Press host Kristen Welker – the latter of which he acknowledged could cause Americans to pay more after riding voters’ complaints about higher prices back to the White House at the expense of Vice-President Kamala Harris.

“I’m going to be acting very quickly. First day,” Trump said in the interview, claiming convicted Capitol attackers had been put through a “very nasty system”.
