Russia has recalled its ambassador to the United States after President Joe Biden said Vladimir Putin would “pay the price” for alleged election meddling and agreed that he was “a killer”. And responding overnight, Putin said “it takes one to know one“. The bad blood follows the release of a declassified US intelligence report that suggested Putin had authorised interference in last year’s presidential election in favour of Donald Trump. The US is expected to impose sanctions on Russia as soon as next week following the report’s conclusions.
