• President Trump paid tribute to fallen American troops on Memorial Day, saying they “died in war so we could live in peace.”

Mr. Trump is trying to contain the fallout from reports that Jared Kushner, his son-in-law and adviser, spoke with the Russian ambassador in December about establishing a secret communication channel to the Kremlin.

Our reporters discovered that federal and congressional investigators are scrutinizing a meeting Mr. Kushner had later that month with a Russian financier whose bank is entwined with Russian intelligence.

As Mr. Kushner’s woes play out in the White House, a different political star is rising: Melania Trump, the first lady.
