The GOP-led Senate’s growing opposition to President Donald Trump’s scheduled tariffs on Mexico is not sitting well with Fox Business Network host Lou Dobbs.

In a scathing monologue Tuesday evening, he blasted Senate Republicans for their cowardice and warned them that their actions could prove disastrous for the country.

Listen via FBN’s “Lou Dobbs Tonight“:

“I’ve talked with a number of people today, all of them off the record, but I can tell you tonight, I fear for the republic,” he said. “The Republican Party is being led on, well, in the U.S. Senate, on Capitol Hill, by cowards. They don’t represent the Americans who sent them there to represent the national interests. Instead, they’re clearly led by multi-nationalists, big business and Wall Street and the lobbies that represent those multi-nationals and business interests.”

As he spoke, images of Senator Majority Leader Mitch McConnell were displayed on the screen.

Earlier Tuesday, McConnell issued a statement to the press warning that “there’s not much support for tariffs” in the Senate and expressing his hope that “tariffs will be avoided.”

Listen:

“In fact, the senators are afraid the president will do exactly what he was voted in to do and what he set out to do — that is, to shut down illegal immigration and secure our southern border,” Dobbs continued.

“To force Mexico to stop the illegal immigration that the chamber of horrors desires for its members. The chamber’s demands of the Senate prove just how afraid big business really is of President Trump, as tonight he is on the verge of winning both a trade war and resolving the national emergency that he declared only four months ago.”

“The Republican Party in the Senate appears, to me, to be on the verge of committing absolute suicide,” the FBN host added. “The tragedy is it may well take this great republic down with them. Tonight President Trump stands between them and the making of what will surely be a national disaster if these GOP senators in the Senate have their way.”

During a closed-door meeting Tuesday between top Senate Republicans and Trump administration officials, Republicans reportedly fiercely pushed back against the president’s plans.

Even Texas Sen. Ted Cruz, a fervent supporter of the president, complained.

“I will yield to nobody in passion and seriousness and commitment to securing the border, but there’s no reason for Texas farmers and ranchers and manufacturers and small businesses to pay the price of massive new taxes,” he reportedly said.

“I want you to take a message back” to the White House, Senator Ted Cruz, Republican of Texas, told the attorneys, according to people familiar with the meeting. “You didn’t hear a single yes.” @CatieEdmondson @maggienyt https://t.co/CvwzTgDReE — Emily Cochrane (@ESCochrane) June 4, 2019

Sen. Ron Johnson went so far as to suggest that the Senate “could muster an overwhelming majority to beat back the tariffs, even if Mr. Trump were to veto a resolution disapproving them,” according to The New York Times.

“The White House should be concerned about what that vote would result in, because Republicans really don’t like taxing American consumers and businesses,” he reportedly said.

House Republicans meanwhile have pledged their support for tariffs.

“House Republicans support the President on Tariffs with Mexico all the way, & that makes any measure the President takes on the Border totally Veto proof. Why wouldn’t you as Republicans support him when that will allow our President to make a better deal.” Thank you @GOPLeader — Donald J. Trump (@realDonaldTrump) June 5, 2019

Following his monologue Tuesday, Dobbs brought Republican campaign strategist Ed Rollins onto the show to discuss the ongoing situation with the GOP-led Senate.

“Here he’s having an extraordinary trip overseas, and the Senate Republicans are basically talking about joining Democrats to override a veto,” Rollins said.

“The bottom line is this president has to be able to stand tough with Mexico as he’s been doing — and all of a sudden you have a message coming out that’s saying we may not support the president’s tariff programs. That, to me, is the beginning of the end if they don’t do that.”

As it stands, tariffs may not even be required. The president threatened Mexico not because he actually wants to impose tariffs on the Latin American country, but rather to incentivize it to take more action against the so-called “migrants” who keep streaming across its border into the U.S.

And the strategy has been working just fine so far. Multiple news outlets confirmed Tuesday that Mexico has begun cracking down on “migrants” because of the president’s threats:

So an article in today’s NYT talked about how Mexico is suddenly cracking down on caravans of illegal immigrants, thanks to Trump’s tariffs. It would seem his strategy may be working. — Durinn McFurren (@DurinnM) June 5, 2019

With Senate Republicans now signaling their intention to block the president’s tariffs, however, Mexico has less incentive to keep cracking down. It’s an extraordinary about-face, especially given all that Senate Republicans owe Trump.

“There would not be a Senate majority if Donald Trump had not run and basically laid out the platform that these people are basically balking on,” Rollins explained. “He is the Republican Party today. He has an extraordinary approval rating among Republicans in this country.”

“At the end of the day, this is the time for them to stand tough with him, because he’s doing what’s in the best interest of this country. It’s what he promised this country. And we have the attention of the Mexicans, and the bottom line is we have the attention of the world, and the strong leader can’t be undercut by his own team.”
