President Donald Trump is scheduled on Tuesday to begin his second state visit to the United Kingdom, where he's expected to meet with various officials, including King Charles.

Trump's European visit comes amid heightened debate by international leaders about how to deal with the threats imposed by Russia's ongoing invasion of Ukraine. Trump last week raised the prospect of potential additional sanctions against Moscow.

And Vice President JD Vance said he planned on Monday to host "The Charlie Kirk Show," a podcast, and would "pay tribute to my friend."
