Trump's New Travel Ban Takes Effect Amidst Heightened Tensions

President Trump's new travel ban has gone into effect, impacting citizens from twelve countries, primarily in Africa and the Middle East. The White House claims the ban is necessary due to these countries' perceived shortcomings in vetting processes, information sharing, and high visa overstay rates. The ban, however, does not affect previously issued visas. The affected countries include Afghanistan, Myanmar, Chad, Iran, and Yemen, among others. This decision has already sparked significant debate and international reaction. The White House press secretary stated, "These measures are crucial for national security and protecting the American people."
