Former Green Party presidential candidate Jill Stein tweeted out the White House phone number on Tuesday calling on her following to "prevent WWIII" by flooding the White House with phone calls and urging them to negotiate with North Korea.

"Urgent. Prevent WWIII. Flood the White House switchboard now: Negotiate don't escalate with North Korea! 202-456-1414," Stein tweeted.

North Korea said on Tuesday that it is examining plans for a missile strike on Guam, just after Trump said that any threat to the United States from North Korea would be met with "fire and fury."

Stein also urged the president to discontinue the trading of threats and "listen to South Koreans, who want diplomacy, not war."
