North Korea on Sunday carried out its most powerful nuclear test yet, an underground explosion that caused tremors that could be felt in China and South Korea. Pyongyang is claiming it tested a hydrogen bomb that can be mounted on an intercontinental ballistic missile capable of reaching the American mainland, and experts say the bomb has destructive capacity far beyond the one that destroyed Hiroshima. President Trump around noon on Sunday tweeted, "I will be meeting General Kelly, General Mattis and other military leaders at the White House to discuss North Korea." He added that "the United States is considering, in addition to other options, stopping all trade with any country doing business with North Korea." More on the situation:
