Chinese surveillance balloons flew over the continental United States at least three times during the Trump years, according to a senior administration official, but their incursions weren’t discovered until after Joe Biden took office.
That gap may help explain why the former president, Donald Trump, and the senior officials who worked for him, denied that Chinese airships entered US airspace on their watch.
Intelligence officials from the Biden administration are willing to provide former Trump national security officials with a briefing about the Chinese surveillance efforts, according to the official, who discussed intelligence matters on the condition of anonymity.
