Ukrainian Ambassador to the UN to take part in Biden’s address to Congress

Ukraine’s ambassador to the United States and a whistleblower who exposed Facebook documents about how the company handles disinformation will be among President Biden’s guests on the floor of the House of Representatives during a speech to Congress, White House officials said on Tuesday.

Ambassador Oksana Markarova and nine other guests will sit in First Lady Jill Biden’s box, officials said, part of a tradition that dates back decades as presidents seek to humanize the policies they talk about in speeches.

Mr. Biden’s speech will take place during fierce fighting in Ukraine, where Russian troops appear poised to launch an all-out strike on Kiev, the country’s capital. Ms. Markarova’s presence at the Capitol highlights the president’s desire to send a signal to President Vladimir Putin that Russia is backing Ukraine from America, even as the fighting continues.

Francis Haugen, a former product manager at Facebook, presented Congress with a slew of internal company documents on how Facebook’s algorithm promotes misinformation and negative messages. In announcing her as a guest, White House officials called her “an advocate for greater humanity and transparency in the tech and social media industry, especially when it comes to teen mental health.”

There will be seven other guests during the speech — a group that White House officials have called “for their resilience, innovation, service, and courage” and said they were chosen because they represent policies or topics that Mr. Biden will refer in his speech.

They include:
