50 years ago, Martina Navratilova left everything in communist Czechoslovakia to start a new life in America.
At that moment, the 18-year-old high school student was one of the most famous defectors of the Cold War, and then became one of the icons of tennis.
Speaking to BBC journalist Amol Rajan, however, she says she fears America "wouldn't allow" her to enter the country now.
"I am not a supporter of US President Donald Trump... I have the impression that America has become a totalitarian state," Navratilova says.
Since Trump took office in January, his administration has been arresting and deporting illegal immigrants, sparking a protests in the land.
Trump has also imposed a travel ban on citizens of 12 countries, and there have been reports of tourists being detained at the border.
"If I were in the same position now as I was in 1975 and had to go live somewhere, I wouldn't choose America, because at this point it's not a democracy," Navratilova says.
As she talks about American politics, her anger becomes apparent.
He believes that people don't notice that the situation is getting worse.
America is "definitely turning against migrants," he adds.
Security services "are kicking people out because they don't fully agree with Donald Trump's agenda... because they don't kiss his ring," he says.

The decision to defect to America in 1975 was not easy, he says.
She had, she says, an "idyllic" childhood in Revnica, now in the Czech Republic, in a loving family that she left behind.
"I didn't know when or if I would see my parents again."
Going to America changed her life.
At a press conference upon her arrival in America, she said that she left Czechoslovakia because she wanted to become number one in tennis, and that she "couldn't do it under the circumstances at home."
She truly became number one - she held the top spot in singles for 332 weeks, and in women's doubles for a record 237 weeks.
Today she is considered one of the best tennis players of all time.
Navratilova has dual citizenship - American and Czech.
He lives with his wife, Julia Lemigov, a model.
Is she worried that in the current political climate, she could lose her citizenship?
"Everything is up in the air right now and that's the whole point."
"Everyone is walking on eggshells, not knowing what's going to happen."
There is, however, one topic that is divisive, and on which she agrees with Trump - the participation of transgender women in sports, she said earlier.
She firmly believes that the inclusion of trans women in women's tennis is "wrong."
It is against the current WTA (women's tennis umbrella organization) rules, according to which a transgender woman can compete in women's tennis if she has a written and signed statement that she is a woman or non-binary person, that she has had testosterone levels below a certain limit for the past two years, and that she has maintained those testosterone levels.
Navratilova believes that trans women have a biological advantage in women's sports, a hotly debated topic.
"There shouldn't be ostracism, there shouldn't be abuse," he says, "but men's bodies should play in men's sports."
"They can still compete. There is no ban on trans women being in sports."
"They just need to compete in the appropriate category, which is the men's category."
"Because of the inclusion of male bodies in women's tournaments, some women don't enter the tournament because a man has taken her place," Navratilova points out.
In December last year, the British Tennis Association changed its rules so that trans women could not compete in certain domestic tennis tournaments.
The British Supreme Court ruled in April that the legal definition of a woman is based on biological sex.
Asked whether tennis should follow the court's decision, Navratilova replied: "100 percent."
When asked further if we should have more understanding for trans people, Navratilova replied: "A lot of understanding, but that still doesn't give them the right to access women's spaces."

"Oh, my God, I'm going to die"
Navratilova has spoken openly about her battle with cancer over the past 15 years.
She was diagnosed with breast cancer in 2010, when she was 52 years old.
It returned 13 years later, along with an unrelated throat cancer.
When she found out, she was in shock.
"I thought, 'This lymph node is a little bigger.' A few weeks later, it was still bigger."
After a scan, doctors discovered a second tumor in her breast.
"We got the results and it was cancer," he says.
"I thought, 'Oh my God, I'm going to die.'"
Although he says the treatment was "hell," he now feels "completely fine."
"Knock on wood, there's none, and there are no side effects, except that red wine still doesn't taste good, so I switched to tequila and vodka," she jokes.
"I'm lucky. The treatment was hell, but afterwards it was great."
Has cancer changed her?
"Cancer taught me to really appreciate each day, which I always did," she says.
"But most of all - he taught me not to worry about the little things."
