House oversight committee says it has evidence that Joe Biden's family received money from China and other countries. The committee's head, James Comer, was supposed to present the evidence at a press conference on May 10.

But the FBI sent Comer a six-page letter explaining why the FBI could not comply with his demand. The documents that Comer and his colleagues did provide to journalists could cause the White House a lot of trouble, writes Frida Ghitis. But Democrats, who have stood up for the elderly president, continue to pretend that nothing is happening, Ghitis says.
