Ted Kaplan is an Orlando pediatrician whose office is covered in artwork from Haiti. He’s been on more than 50 trips there, working on medical missions and trying to support the medical care on the island.

“In general, it’s hard to get stuff in and out of the country,” he said. “A lot of times, people carrying it is the way that we have to do it.”

Although he loves the country, the culture and the people, Kaplan took his last trip to Haiti in 2018. He said safety became a larger concern for him and his wife, and it got more dangerous after his last visit.

“First, it was a lot of street protests and blocked roads. It sometimes created difficulty getting around, and it’s a little bit scary for people who aren’t used to it,” Kaplan said.

Haiti, along with other 11 countries, are included in a proclamation signed by Trump, banning travel from countries such as Afghanistan, Iran and Sudan.

It was signed after an antisemitic attack in Boulder, Colorado.

“I directed the Secretary of State to perform a security review of high-risk regions and make recommendations on where restrictions should be imposed,” said Trump as he signed the proclamation.

The president said the ban will protect national security by not allowing travelers into the U.S. from countries with deficient vetting and screening.

It also places partial restrictions on seven other countries, including Cuba and Venezuela.

Trump said the list is subject to change.

He can revise it if conditions improve, or add new countries as “threats emerge around the world.”

After speaking to people in Haiti, Kaplan said they feel disrespected.

“It’s just like another insult to injury, or blow to people when they’re down,” he said.

There are some exceptions to Trump’s travel ban, such as lawful permanent residents of the U.S., an athlete traveling for a major sporting event, and certain visas and existing visa holders.
