Columbia, SC (WLTX) -- The current showdown between the U.S. and Iran, the battle over tariffs and a new immigration plan are making headlines across the globe.

Friday, Senator Lindsey Graham answered questions from the media on these topics.

Graham began his interview talking about President Trump's new immigration proposal. He says he met with the president to discuss the plan Thursday.

"We need a strong, secure border," said Graham. "The president's plan makes sense to me and I support it."

Graham, too, introduced legislation Wednesday to fix an overflow of immigrants coming to the U.S. from Central America. 

"We've got a problem at the border we've never had before," he said. "If you come to America and you ask for asylum, you're entitled to a hearing. It takes three or four years to have a hearing scheduled. Nobody shows up to the hearing."

His proposal is that Central American asylum applications must be made in the immigrant's home country instead of a surrender on the U.S. border.

"It's out on the streets in Central America that if you come to America and ask for asylum, you'll be let loose in the country. We can't hold somebody three or four years," he said.

Graham's plan would allow children to be sent back to their countries, and instead of children and families being released after a 20-day hold, he wants to change it to 100 days. Graham says that time extension is better for officials to process an asylum claim.

His plan also involves hiring 500 new immigration judges to help remedy the current backlog of 900,000 cases.

"A wall will not fix this problem. [These immigrants are] trying to get caught," said Graham. "My goal is to change our laws to put smugglers out of business. We can't go much longer. This is not a crisis. It's a disaster."

Graham spoke next on the Iran Nuclear Deal.

"Now they're challenging Trump. President Trump is being tested by North Korea, by China, by Iran, by [Nicolás] Maduro and by Syria," he said. "It bothers me greatly to read in the paper the internal conflict going on about how to deal with Iran."

Graham says he appreciates the president getting out of the Iran Nuclear Agreement, adding that he believes Iran can have nuclear power like other countries, but without the ability to make their own fuel for bombs.

"I don't want a war with Iran, but I want Iran to understand if they choose to attack us there will be a war and they will lose it," he said. "I want Iran to know their days of running wild in the mid-east are over."

The ongoing dispute between the U.S. and China over tariffs continues.

China said Monday it would slap tariffs on more than 5,000 U.S. Products in retaliation of the president's decision to raise duties on Chinese goods.

Caught in the middle of the trade war are not just consumers, Graham says, but farmers, too.

"Farmers are always on the tip of a spear in any trade war. To the farmers, I'm trying to get the president to do a disaster bill that will help you and I hope we pass one next week," said Graham. "South Carolina farmers have been devastated by these floods and we're gonna get something done next week."

While the U.S. and China continue to negotiate, the trump administration has lifted tariffs on Mexican and Canadian goods.

"If we don't take China on now, stop the way they're doing business, they're going to destroy our economy over the next 50 to 100 years," he said. "Tariffs are hurting BMW, they're hurting Boeing, but they're also hurting China. It's not too much to ask the Chinese to stop cheating. They're never going to stop unless somebody makes them."
