The Trump administration pressured multiple countries to withdraw their sponsorship of a leading European conference on disinformation, with Canada, Lithuania and the EU’s diplomatic service subsequently agreeing to do so, the Guardian understands.

The conference, #Disinfo2026, taking place Wednesday and Thursday, is the annual meetup of Europe’s counter-disinformation community and has drawn hundreds of researchers, journalists, technologists and policymakers to a hotel in Vilnius, Lithuania. It is run by an independent Brussels non-profit, EU Disinfo Lab.

Days before the conference, the logos of its main supporters – the Lithuanian ministry of foreign affairs, the European External Action Service (EEAS) and Global Affairs Canada, the country’s foreign ministry – were wiped off its website.
