Trump will be heading to Rome for Pope Francis' funeral and said he'd like to meet with other world leaders about trade.

"They all want to meet and they want to meet about trade, and we are making some great inroads and great deals," he claimed.

A new Associated Press-NORC Center for Public Affairs Research poll published on Thursday found about half of voters opposing tariffs on all goods entering the United States, although about 1 in 5 U.S. adults neither favor nor oppose them.

Asked if they favor or oppose the policy of placing tariffs on "all goods" coming into the U.S., adults were actually split, with 52% of respondents opposing the move, 27% in favor and 21% neither favoring nor opposing the policy.

Plus, 76% of respondents said the tariff policies will increase the price of consumer goods, while 11% said they will decrease prices and 12% said they’ll have no effect on prices.

On Trump's handling of the economy overall, 61% of respondents disapproved, while 37% approved.

Trump pushed back on China after Beijing's Foreign Affairs Ministry called the administration's assertions that tariff talks are happening "fake news."

"Well, they had a meeting this morning, so I can't tell you," Trump began to say before a reporter pressed him on who was the "they" he referred to.

"It doesn't matter who 'they' is. We may reveal it later, but they had meetings this morning, and we've been meeting with China," Trump said, before going on to criticize the reporter who asked the question.

Trump suggested in a Truth Social post on Thursday that Boeing should default on China following its decision to halt deliveries and return planes due to tariffs.

"This is just a small example of what China has done to the USA, for years," he wrote.

The president also continued to allege fentanyl is pouring into the United States from China, Mexico and Canada.

"[I]t better stop, NOW!" he posted.
