Judge orders Giuliani to testify to Georgia grand jury, suggests he take "train or a bus or Uber" if he can't fly

If former New York City mayor Rudy Giuliani can't fly to Atlanta for court-ordered testimony before a grand jury investigating Donald Trump, he'd better find another way to get there, a judge suggested Tuesday.

Giuliani had been ordered to appear to testify Tuesday before Fulton County's special grand jury investigating Trump's efforts to overturn the election, but on Monday filed an emergency application to postpone his appearance. His lawyers cited a doctor who said Giuliani is unfit for air travel following a heart stent operation earlier this summer.

Fulton County Judge Robert McBurney, who is overseeing the special grand jury, held a hearing on the request Tuesday and ordered Giuliani to appear for grand jury testimony on Aug. 17.
