Sen. Maria Cantwell, D-Wash., responded to Majority Leader John Thune’s suggestion on Monday that her and Sen. Chuck Grassley's tariff bill likely has "no future" in the Senate, claiming that the Republican "doesn’t want to listen" to constituents and colleagues sounding the alarm on Trump's trade policies.

"Sen. Thune doesn't want to listen," Cantwell told reporters on Monday evening. "We got more endorsements today from organizations, consumer groups, who are really impacted by this. ... So now we have inflation, and we have business anxiety, and we have a very unpredictable situation, so it's affecting our economy and it's affecting consumers. I would hope my colleagues would listen."

Despite Thune's assertion that he wouldn't bring up the bipartisan tariff bill, Cantwell said there was still some movement on her proposal.

"I talked to our House colleague who's planning on dropping a bill, so I'm sure he's going to continue to proceed. So, this is about having a discussion on something that's the constitutional authority of Congress. I think people should want to do that responsi[bly] and have that conversation,” she said.

Cantwell is expected to question U.S. Trade Representative Jamieson Greer during a hearing of the Senate Finance Committee on Tuesday morning. She said she expects to ask him, "Where was the consultation with Congress about this?" and, "Where's the homework done by the administration to not misconstrue the authority that was given?"

Treasury Secretary Scott Bessent told Fox Business there have been "50, 60, maybe almost 70, countries now who have approached" the U.S. about the tariffs.

"As I advised on many shows on April 2, I suggested that the foreign officials keep your cool," he said. "Do not escalate and come to us with your offers on how you're going to drop tariffs, how you're going to drop non-tariff barriers, how you're going to stop your currency manipulation, how you're going to stop the subsidized financing. And at a point President Trump will be ready to negotiate."

Bessent weighed in on talks with Japan, saying that after the president's call with Prime Minister Shigeru Ishiba earlier Monday, Trump asked Bessent and U.S. Trade Representative Jamieson Greer to take the lead on negotiations.

"Japan is a very important military ally. They're a very important economic ally, and the U.S. has a lot of history with them. So I would expect that Japan is going to get priority just because they came forward very quickly," Bessent said. "But it's going to be very busy, and President Trump, again, gave himself maximum negotiating leverage, and just when he achieved the maximum leverage, he's willing to start talking."

Pressed on if he believed a deal could be struck with Japan in the next week or two to help the markets, Bessent didn't answer directly, only suggesting that "negotiations are going to be tough."

The Dow Jones Industrial Average fell for a third day following the tariff rollout and Trump's threat to raise tariff rates on China.

The Dow posted its largest intraday point swing ever -- falling more than 1,700 points during its Monday session low, then swinging up 2,595 points from low. The Dow dropped 349.26 points, or 0.91%, to close at 37,965.60.

For the S&P 500 Index, Monday's 8.5% high/low spread has only happened 20 other times since 1962, according to S&P Global. The S&P 500 briefly entered bear market territory during the session but was last off nearly 18% from its recent high. It shed 0.23% to end at 5,062.25.

House Minority Leader Hakeem Jeffries stressed Democrats will continue to “push back” in a bipartisan way to fight Trump's tariffs.

“The Constitution is very clear that tariffs and tax policy, the ability to raise revenue, that authority is vested in the Congress for a reason,” Jeffries said. “The Congress is most closely associated, particularly the House, with the American people.”

Jeffries said Congress has to start acting like a separate and co-equal branch of government. He decried Republicans for conceding to Trump and said the cost of living in America has gotten “too expensive” under the Trump administration.

“What we have witnessed under complete Republican control of government is a willingness to simply bend the knee to Donald Trump, no matter how much pain he is inflicting on the American people or how much damage Trump is doing to the American way of life,” he said.

Jeffries also slammed the president for harming American families and causing an “economic disaster.”

“This is a reckless economic sledgehammer that Donald Trump and compliant Republicans in the Congress are taking to the economy, and the American people are being hurt. Enough.”

Ahead of United States Trade Representative Jamieson Greer’s appearance on Capitol Hill, the leader said he hopes Greer can confirm if the president’s tariffs are an intentional scheme to enrich the wealthy.

“The Trump tariffs, which are a tax on the American people, are so reckless, so unstrategic, so lacking in any sophistication, that the only conclusion that one can draw is that Donald Trump and Republicans are intentionally tanking the economy,” he said. “Is it because, as Donald Trump has indicated, that during tough economic times, the rich get richer, and it's a buying opportunity?” he asked.
