ATLANTA (AP) — Donald Trump is showing no signs of curbing his battle with a Fox News television host, the Republican Party establishment and several presidential primary rivals who are accusing him of disrespecting women.

Even a former Trump campaign aide suggests that the businessman’s bid for the White House has become a side show.

Trump’s unconventional, insurgent campaign has excited many anti-establishment conservatives while confounding Republican Party leaders already facing the prospects of a bruising fight among 17 candidates.

His “blood remark” about a Fox News debate moderator Megyn Kelly which aired on CNN cost him a prime-time speaking slot at an Atlanta conference where several other presidential candidates spoke to about 1,000 conservative activists.

The Trump campaign has retorted by calling the conference’s organizer a “total loser” who backs other “establishment losers.”
