The threat of a Russian invasion of Ukraine has placed heightened importance on the United States' and NATO's defenses across eastern Europe, which for decades have acted as a buffer between Russia and the West.
NATO has four multinational battalion-size battlegroups in Estonia, Latvia, Lithuania and Poland, which operate on a rotational basis. Each is led by the UK, Canada, Germany or the US, and contains troops from several member countries. The alliance said last month that all four groups are "robust and combat-ready forces."
Tulsi Gabbard, Donald Trump’s pick to lead the intelligence community, was briefly placed on a Transportation Security Administration list that prompts additional security screening before flights after her overseas travel patterns and foreign connections triggered a government algorithm earlier this year, three sources familiar with the matter told CNN.
