Mark Brzezinski, son of former US national security advisor Zbigniew Brzezinski, has been sworn in as US ambassador to Poland. Vice President Kamala Harris conducted the ceremony on Wednesday, which was attended by Brzezinski’s sister Mika and brother-in-law Joe Scarborough, both hosts of MSNBC’s Morning Joe.
Brzezinski, who previously served as US ambassador to Sweden from 2011 to 2015, was nominated for the position in August and confirmed by the Senate last month.
