President-elect Donald Trump’s choice of Tulsi Gabbard as U.S. intelligence chief has sent shockwaves through the national security establishment, adding to concerns that the sprawling intelligence community will become increasingly politicized.

From blaming NATO for the Ukraine war to echoing Russian propaganda, Gabbard has ruffled feathers inside the spy agencies she could soon lead.

Tulsi Gabbard - a former Democratic congresswoman who joined the Republican Party to back Donald Trump - is the president-elect's pick for director of national intelligence. The wide-ranging role would mean she oversees US intelligence agencies like the CIA, FBI and the National Security Agency (NSA), which focuses on intelligence gathering.
