President Donald Trump credited his "powerful" steel tariffs for the opening of a future steel plant.
Watch in our video player above.
The president touted the 50% tariffs on steel imports that he imposed last year as the impetus for the steel plant that officials announced Monday will be built in Iowa by Mesabi Metallics.
"Our steel industry is roaring back to life. Everyone is building their plants here because they don't want to pay tariffs," Trump said in the Oval Office. "It's really not that complicated."
Trump says he'll stump in Iowa again ahead of midterms
"I'm going to come to Iowa," Trump said in the Oval Office announcing a new $15 billion steel plant there, after talking with Rep. Ashley Hinson about her Senate campaign there.
"We're going to do a great rally and we'll all be there together," Trump said. "We have to get you all elected."

Both Trump and Vance have already campaigned with GOP candidates in Iowa, and their continued attention on the state reflects the administration's understanding that governor and Senate races have become competitive.
Trump has vowed to campaign in 35 of the most competitive battleground races in the final sprint to November's midterm elections. He plans on Saturday to visit Ohio in support of Sen. Jon Husted, following stops in Oklahoma and Alabama in the preceding days.
"I love Iowa," Trump said.
Trump says U.S. ambassador to China 'probably' meant U.S. selling to Taiwan — not China
Asked about Ambassador David Perdue's comment on Fox News Channel's "Fox News Sunday," Trump said, "I never heard of that one."
On Sunday, Perdue said that Trump had asked Chinese President Xi Jinping if he wanted to buy weapons from the United States. Such an offer would upend generations of U.S. policy toward China and Taiwan and expose U.S. technology to a potential foe.

Perdue's remark came days after Trump hosted Xi for a state visit in Washington. Perdue didn't specify when the offer was made.
On Monday, Trump said he was "going to have to ask" Perdue about the comment, trying to correct the reporter who asked about it — and suggesting that surely Perdue had meant arms sales to Taiwan, not China.
Trump disagrees with bail for men arrested near U.S.-run air base in UK
Trump said he was "surprised" that the five young British men arrested Sunday on explosives and terror charges near the base in England were allowed to be released.
A U.K.-owned base, RAF Fairford has been used by American bombers during decades of conflicts in the Middle East, including this year's war with Iran.

The men were released on bail on Monday, and counterterror detectives said they were investigating "multiple lines of inquiry," including whether there was a link to Iran.
"I know the answer," Trump said, when asked if there were a connection to Iran. "I can be very specific, but I'd rather not say it."
