Trump nominee elected as new NASA chief in 50-49 vote

US President Donald Trump's nominee James Bridenstine was confirmed as NASA's 13th administrator after two days of voting, which saw a senator switching his decision to break the 49-49 tie. NASA had spent 15 months without a permanent chief, longest in the space agency's history. The 42-year-old former Navy pilot would be the first NASA chief with a non-scientific background.
