Vice President Kamala Harris had another call with a foreign leader Tuesday, independent of President Biden.

Prior to Tuesday’s solo call, Harris also took calls alone with French President Emanuel Macron and Canadian Prime Minister Justin Trudeau as well as Israeli Prime Minister Benjamin Netanyahu, shortly after the president put in a call to the French and Canadian leaders himself.

Less than two months into the new administration, Harris’s frequent solo calls with world leaders signal that she’ll engage deeply even in foreign policy, though her experience has been almost entirely in the domestic realm.

“She will be seen by everyone as a potential president in waiting,” one European ambassador told Politico in February. “Much more than in previous presidencies.”

Vice President Kamala Harris also participated in the first bilateral meeting of the new administration, between the U.S. and Canada, an opportunity not afforded to Biden during his time in Harris’ job.
