HAMBURG, Germany — First lady Melania Trump was forced to cancel her participation in a climate event because of protests at the G-20 summit Friday, the White House said.
Her spokeswoman, Stephanie Grisham, told USA TODAY that Hamburg police were unable to clear the streets enough for Mrs. Trump's delegation to head to the event.
"She was supposed to participate in the spousal program and was very much looking forward to it," she said.
Joachim Sauer, the husband of German Chancellor Angela Merkel and a chemist, had planned an event for spouses of world leaders at the German Climate Computing Center.
The leader's spouses are also invited to attend a performance of Beethoven's Ninth symphony at the Elbphilharmonie concert hall Friday night, and a tour of the city Saturday.
Thousands of protesters shut down streets throughout Hamburg's central city on Friday morning, as rioters burned cars and clashed with police.
"Thinking of those hurt in #Hamburg protests. Hope everyone stay safe!" Mrs. Trump tweeted Friday morning from the German government guest house where the Trumps are staying in Hamburg.
