German Chancellor Angela Merkel came to Ivanka Trump's defense after political types and journalists were alarmed to see the first daughter briefly sitting in for her father at a table with world leaders at the G-20 summit in Hamburg, Germany.

"Ivanka Trump belonged to the American delegation, so that is in line with what other delegations do. And it is known that she works at the White House and carries responsibility for certain initiatives," Merkel told reporters on Saturday at the end of the event, according to the Associated Press.

Merkel was spotted in a photo posted to Twitter by Russian G-20 sherpa Svetlana Lukash showing Ivanka Trump, who is also an adviser to her father, sitting at a table between President Xi Jinping and British Prime Minister Theresa May. The tweet was later deleted, but according to Bloomberg, Trump sat in for the president at least twice on Saturday as the president left for one-on-one meetings with leaders. She reportedly did not speak during these occasions.

Ivanka did speak briefly at a World Bank symposium dedicated to women's entrepreneurship before the president arrived on Saturday.

"I'm very proud of Ivanka who has been a forceful advocate for landmark women entrepreneurs. And she worked very hard for the women entrepreneurs finance initiative," Trump later said of his daughter at the event.
