United States Acting Ambassador at the U.S. Embassy in London Lewis Lukens commended London Mayor Sadiq Khan on Sunday, the day after another terror attack on the United Kingdom left seven dead and many more injured, and just hours after U.S. President Donald Trump had tweeted criticism of the London Mayor.

Lukens is currently the Acting Ambassador for the U.S. in the U.K. He took over after the departure of Ambassador Barzun. Lukens served as the State Department’s Diplomat in Residence for the Northwest at U.C. Berkeley from 2014-2016 under the Obama Administration.

London’s first Muslim mayor issued a statement in which he informed Londoners that there is “no reason to be alarmed” as the city increases its police presence in response to Saturday’s terror attack.

“Londoners should be aware that there will be additional armed and unarmed police officers on our streets from tonight in order to keep Londoners, and all those visiting out city safe,” said Khan. “I want to reassure all Londoners, and all our visitors, not to be alarmed. Our city remains one of the safest in the world.”

In an early Sunday morning tweet President Trump responded to the London Mayor’s statement:

Hours later, the U.S. Embassy in the U.K. tweeted out comments from Acting Ambassador Lukens. The first two of a series of three tweets containing Lukens’ comments merely offered condolences and support for the people affected in the London attacks, but the third included a commendation of the London Mayor despite the fact that the President had already made comments regarding Mayor Khan.

President Trump’s Director of Social Media tweeted at Mayor Khan the same morning as Trump’s tweet :

The London Mayor tweeted of Trump in May 2016:

The U.S. Embassy and Consulates in the United Kingdom website states in a profile of Lukens, “As Executive Director of the Department of State’s Executive Secretariat from 2008-2011, he directed all management support for Secretary of State Hillary Clinton, including her overseas travel.”
