President Trump on Wednesday took aim at the United Kingdom’s intelligence agencies — just after it was announced he would visit the U.K. in June.

“‘Former CIA analyst Larry Johnson accuses United Kingdom Intelligence of helping Obama Administration Spy on the 2016 Trump Presidential Campaign.’” @OANN WOW! It is now just a question of time before the truth comes out, and when it does, it will be a beauty!” Trump tweeted early Wednesday morning.

Former CIA analyst Larry Johnson, who has previously argued that the U.K has spied on Trump during the 2016 election, has historically argued that that the CIA, not Russia, could have been responsible for hacking the Democratic National Committee.

Meanwhile, special counsel Robert Mueller’s Russia report, released last Thursday, outlines efforts from Russian military intelligence services to hack into computers and obtain documents from people within the Democratic Party and Hillary Clinton’s presidential campaign. Such documents were shared with DCLeaks and Guccifer 2.0, along with WikiLeaks for publication.

Trump and first lady Melania Trump are slated to visit the U.K. from June 3-5, per the request of Queen Elizabeth II. Trump will also attend a bilateral meeting with British Prime Minister Theresa May, along with a ceremony to commemorate the 75th Anniversary of D-Day.
