CLAIM: During President Donald Trump's first State of the Union (SOTU) address in his second term, the president said he is overseeing the "most secure border in American history." VERDICT: Mostly true. Trump has overseen the lowest levels of illegal immigration to the United States in more than half a century. "After four years in which millions and millions of illegal aliens poured across our borders, totally unvetted and unchecked, we now have the strongest and most secure border in American history — by far," Trump said at the address. "In the past nine months, zero illegal aliens have been admitted to the United States," Trump continued.
