russia investigation

Secret Service Agents and staff stand by the limo of Vice President Mike Pence, at the West Wing of the White House, Friday March 22, in Washington, as news breaks that the special counsel Robert Mueller has concluded his investigation into Russian election interference and possible coordination with associates of President Donald Trump. The Justice Department says Mueller delivered his final report Friday to Attorney General William Barr, who is reviewing it. Mueller's report, still confidential, sets the stage for big public fights to come. The next steps are up to Trump's attorney general, to Congress and, in all likelihood, federal courts.
