evidence: President Joe Biden on Wednesday again avoided questions about an investigation into documents marked classified found at his home and office, six days after a special counsel was named to investigate the matter. [...] Press secretary Karine Jean-Pierre and a spokesperson for the White House counsel's office, Ian Sams, have repeatedly referred reporters' questions to the Justice Department, which itself has not shared much information. [...] The president himself has addressed the topic just twice since a news report on Jan. 9 made public the fact that documents marked classified had been found at an office he used after he left the vice presidency.
