CNN package appeared to be \'live explosive device\'

ROUGH CUT (NO REPORTER NARRATION) NYC Police Commissioner James O'Neill told New New Yorkers a suspicious package sent to CNN contained a "live explosive device" and "white powder" on Wednesday.

Mayor Bill de Blasio said the city will "not be intimidated" by what he described as an attempt to terrorize the city.

Police intercepted suspected explosive devices sent to former U.S. President Barack Obama, former Democratic presidential candidate Hillary Clinton and the CNN bureau in New York that apparently targeted figures disparaged by right-wing critics two weeks before U.S. congressional elections.

With the country deeply polarized under President Donald Trump, the packages brought a new level of tension to political contests that will decide whether Democrats can challenge the majorities now held by Trump's Republicans in Congress.
