That’s a lot of flagged contributions :
The Federal Election Commission sent a letter  to the Democratic presidential candidate’s campaign committee on Thursday with a 90-page spreadsheet listing 3,457 “excessive, prohibited, and impermissible contributions.”
The campaign’s January financial disclosure filing listed contributions from foreign nationals and unregistered political committees, the FEC said. Other contributions came from donors who exceeded the $2,700 per-election limit.
