The blimp’s creators say they plan to fly it this week outside Parliament during Trump’s state visit. The museum says it hopes to add the Trump blimp to its collection, along with an inflatable depicting London Mayor Sadiq Khan that has been flown by Trump supporters.

The museum says it “hopes to reach out to both creators shortly.”The president and the mayor have clashed in public, with Trump labelling Khan a “stone cold loser” in a tweet on Monday. Khan’s spokesman said “childish insults … should be beneath the President of the United States.”

Khan has been a frequent critic of Trump and gave permission for an inflatable blimp depicting the president as a screaming baby to be flown near Parliament during the president’s trip to the U.K. last year. Protesters plan to fly the blimp again during Trump’s three-day state visit. Khan supporters call Trump racist for his attacks on London’s first Muslim mayor.
