It was a public relations battle featuring two well-known masters of the media, a beauty queen and a controversial topic.
On the East Coast was Trump, whose fortune and brand is boosted by his ability to navigate storms of controversy.
On the West Coast was Allred, legendary for her ability to draw hordes of cameras to her Beverly Hills law office to capture her outrage over alleged injustices done to her clients.
The client is Jenna Talackova, a 23-year-old, 6-foot-1-inch tall blond Canadian, who underwent sexual reassignment surgery four years ago.
Talackova won a regional beauty crown qualifying her for Canada's national title, but she was then told the May 19 Miss Canada Universe pageant in Toronto was only open to "naturally born females."
"I am a woman," Talackova said in a prepared statement she read to reporters in Allred's conference room Tuesday. "I was devastated and I felt that excluding me for the reason that they gave was unjust."
Allred's statement attacked Trump for questioning Talackova's sexuality.
"She did not ask Mr. Trump to prove that he is a naturally born man or to see photos of his birth to view his anatomy to prove that he was male," Allred said.
How she became a female is not important, she said.
"The Miss Universe competition is designed to find the one person in the world whose human qualities make them worthy of the Miss Universe crown and title," Allred said. "Jenna is beautiful in every way. Her life story will undoubtedly inspire people throughout the world."
Talackova, in a 2010 interview, said she knew she was a girl at age 4. She said she started hormone therapy at age 14 and underwent sexual reassignment surgery at 19.
Trump, warned of Allred's attack when the lawyer alerted reporters Monday afternoon that she would hold the news conference, shifted his pageant's position in an announcement Monday night.
Talackova could compete provided "she meets the legal gender recognition requirements of Canada, and the standards established by other international competitions," the Miss Universe Organization said.
Trump's maneuver didn't appear to temper Allred's outrage.
"The last-minute statement by Mr. Trump's representative put out late yesterday only confuses the issue," she said. "Instead of stating clearly that Jenna will be allowed to compete, Mr. Trump qualifies it by adding conditions that are ambiguous."
She asked Trump for "a clear answer -- not a wimpy, wishy-washy type of answer -- but something that we can take to the bank."
Allred didn't know it then, but Trump gave a clearer statement to CNN in New York two hours earlier.
"We went by the laws of Canada and the laws of the United States, and those laws say that she should be allowed to enter the pageant," Trump said. "So she will be entering the Miss Canada pageant."
When read Trump's new statement, Allred paused for several seconds and said "I stand by my statement. We want this rule eliminated."
