President Trump ramped up his trans-Atlantic feud with London Mayor Sadiq Khan on Tuesday, firing back after Khan mocked the commander-in-chief over the weekend, saying he was “dealing with a hurricane out on the golf course.”

“The incompetent Mayor of London, Sadique [sic] Kahn, was bothered that I played a very fast round of golf yesterday. Many Pols exercise for hours, or travel for weeks. Me, I run through one of my courses (very inexpensive). President Obama would fly to Hawaii,” Trump tweeted.

“Kahn should focus on…….’knife crime,’ which is totally out of control in London. People are afraid to even walk the streets. He is a terrible mayor who should stay out of our business!” the president continued.

The Sun reported Monday that there had been 90 violent murders, most of them stabbings, in London so far in 2019.

In contrast, there have been 285 mass shootings in the US since the start of the year, according to Gun Violence Archive, which tracks gun violence.

Khan trolled Trump for skipping out on a visit to Poland to commemorate the Nazi invasion of the country, which launched World War II, to direct the response to the powerful Hurricane Dorian from Camp David.

But the president also hit the links at his Virginia club during the weekend.

“He’s clearly busy dealing with a hurricane out on the golf course,” Khan told Politico.

Trump’s spokeswoman said the president was constantly briefed by aides on the storm’s progress while at the club.

Khan also knocked the president for supposedly encouraging racists with his tough rhetoric on immigration and attacks on people of color in Congress.

Trump, he wrote in the Observer on Sunday, was the “global poster-boy for white nationalism,” the Guardian reported.

The pair have been at each other’s throats since 2016, when then-candidate Trump announced that he would impose a total ban on Muslim immigration, which Khan, a Muslim, called “ignorant.”

In June, Trump called Khan a “stone cold loser” on Twitter, and London’s mayor shot back, calling Trump’s tweets worthy of “an 11-year-old.”
