Boris Johnson congratulates Biden despite Trump's refusal to concede

British Prime Minister Boris Johnson joins a growing list of foreign heads of state to congratulate Biden despite Trump's continued refusal to concede.

Johnson tweeted Tuesday afternoon that the two discussed their "shared priorities – from tackling climate change, to promoting democracy, and building back better from the coronavirus pandemic."

A Downing Street spokesperson told pool reporters Johnson and Biden discussed the countries' partnership through NATO -- an alliance Trump has repeatedly slammed.

Johnson also invited Biden to attend the COP26 climate change summit that the United Kingdom is hosting in Glasgow next year and said he also looks forward to seeing him when the UK hosts the G7 Summit in 2021, according to the spokesperson.
