MSM chose not to report the Anti-Defamation League statement (ADL says Bannon is not anti-Semitic BTW) about Ellison nor did it report that he was one of 8 members of Congress to vote against Iron Dome, an anti-missle system that protected Israeli civilians from Hamas rockets.
EDIT: After the DNC election which Ellison lost, the Wall Street Journal disclosed the following:
"Mr. Ellison, who is an African-American Muslim, also faced complaints about his past associations with the Nation of Islam and statements he has made that were perceived as criticizing Israel. Haim Saban, an Israeli-American donor who funded the construction of the DNC’s Washington headquarters, in December publicly called Mr. Ellison “clearly an anti-Semite.”"[4]
But they should have disclosed this information before the election.
