First Read is your briefing from "Meet the Press" and the NBC Political Unit on the day's most important political stories and why they matter.
WASHINGTON — "Nasty" might be the perfect word to describe President Trump's arrival in London for his state visit to the United Kingdom.
After calling Meghan Markle, the duchess of Sussex, "nasty" (yes, there's a recording), the president also lobbed the word at London's mayor - right before he touched down in Britain.
".@SadiqKhan, who by all accounts has done a terrible job as Mayor of London, has been foolishly "nasty" to the visiting President of the United States, by far the most important ally of the United Kingdom. He is a stone cold loser who should focus on crime in London, not me......"
He followed up by singling out Khan's stature.
"....Kahn reminds me very much of our very dumb and incompetent Mayor of NYC, de Blasio, who has also done a terrible job - only half his height. In any event, I look forward to being a great friend to the United Kingdom, and am looking very much forward to my visit. Landing now!"
Days earlier, Khan argued that Britain shouldn't be rolling out the red carpet for Trump, writing that the president's "divisive behaviour flies in the face of the ideals America was founded upon - equality, liberty and religious freedom."
After arriving in London, Trump also attacked CNN and new parent company AT&T - obviously after watching some cable TV.
"I believe that if people stoped [sic] using or subscribing to @ATT, they would be forced to make big changes at @CNN, which is dying in the ratings anyway. It is so unfair with such bad, Fake News! Why wouldn't they act. When the World watches @CNN, it gets a false picture of USA. Sad!"
Afterward, Trump met with the Royal Family at Buckingham Palace.
And later today, Trump tours Westminster Abbey, has tea with Prince Charles and participates in a state banquet with the queen.

Mulvaney admits Russia interfered in '16 election
On "Meet the Press" yesterday, acting White House Chief of Staff Mick Mulvaney admitted that Russia interfered in the 2016 election.
"The answer to the short question is, yes. Russia did attempt to interfere in our election. There's no question. Let's not lose sight of the fact that it was the previous administration that let that happen," he said.
But let's also don't lose sight of the fact that Team Trump WELCOMED that Russian interference, and that it never picked up the phone to notify the FBI about Russia' outreach.
- Donald Trump Jr., Paul Manafort and Jared Kushner met with a Kremlin-connected lawyer on June 9, 2016 after Donald Trump Jr was told that the Russian government had dirt on Hillary Clinton.
- Trump himself asked Russia for assistance in the 2016 election: "If you're listening, I hope you're able to find the 30,000 emails that are missing."
- A Trump campaign associate - presumably Roger Stone - communicated with Russian intelligence.
- Stone appeared to have advance notice of the WikiLeaks releases of John Podesta's emails before they first came out on Oct. 7, 2016: "It will soon [be] the Podesta's time in the barrel."
- And Trump eagerly campaigned on the WikiLeaks disclosures of Podesta's emails, mentioning the word "WikiLeaks" some 140 times in the final month of the race.
Don't forget what the Mueller report said: "[T]he investigation established that the Russian government perceived it would benefit from a Trump presidency and worked to secure that outcome, and that the Campaign expected it would benefit electorally from information stolen and released through Russian efforts."
2020 Vision: Golden State of mind
Nearly the entire Democratic field was in California over the weekend - with one big exception.
Bernie Sanders took aim at Joe Biden's absence, per NBC's Gary Grumbach, Deepa Shivaram and Ben Pu.
"As you all know, there is a debate among presidential candidates who have spoken to you here in this room and those of who have chosen for whatever reason not to be in this room," Sanders said.
Julian Castro, meanwhile, received his loudest applause during his criminal justice reform pitch.
And John Delaney got booed for two-straight minutes after he said "'Medicare for All' may sound good, but it's not good policy."
Oh, and a man interrupted Kamala Harris' speech and grabbed her microphone before being escorted out.

Two out of three.
That's the number of Democratic gubernatorial candidates this cycle who back tough abortion restrictions — at odds with the rest of the party.
In this off-year, gubernatorial races will be held in Kentucky, Louisiana and Mississippi.
In Louisiana, incumbent Democratic Gov. John Bel Edwards just signed one of the strictest anti-abortion bills in the country. And in Mississippi, expected Democratic nominee Attorney General Jim Hood is defending that state's new anti-abortion law in court.
