WASHINGTON (AP) — Special counsel Robert Mueller's investigation into Russian contacts with President Donald Trump's campaign has gained access to thousands of emails sent and received by Trump officials before the start of his administration, according to several people familiar with Trump's transition organization. But the investigators did not directly request the records from Trump's still-existing transition group, Trump for America, and instead obtained them from the General Services Administration, a separate federal agency that stored the material, according to those familiar with the Trump transition organization. The tens of thousands of emails in question pertain to 13 senior Trump transition officials.
