WASHINGTON – Ivanka Trump is planning a trip to Germany to attend a summit on the economic empowerment of women, a senior administration official said Sunday. The first daughter was invited by German Chancellor Angela Merkel during Merkel’s recent White House visit, said the official, who was not authorized to discuss details of the trip by name and requested anonymity. The W20 summit, a women-focused effort within the Group of 20 countries, will be in Berlin in late April. Ivanka Trump’s plans are still being worked out, but she hopes to study successful apprenticeship programs during her visit.
