Biden's own ambassador to Mexico weighed a primary challenge over border failures, faults Harris in new book

Ken Salazar, the man Joe Biden trusted to represent the United States in Mexico City, grew so frustrated with his own administration's refusal to confront the border crisis that he quietly assembled a campaign team and drafted a presidential platform to run against his boss. He never pulled the trigger, but the fact that Biden's hand-picked ambassador got that far tells you everything about the scale of the Democratic Party's border denial.

Salazar's account, drawn from his forthcoming book "Borderlands: My Fight For An Inclusive America," lands like an insider's indictment of an administration that spent years dodging the word "crisis" while one raged on the southern border. Fox News reported on excerpts obtained by Politico that reveal Salazar begged for a border czar, urged officials to call the situation what it was, and ultimately watched the Democratic Party hand its nomination to a vice president he says accomplished nothing on migration.

The revelations matter now because they come from inside the house. This is not a Republican attack ad. It is a former Democratic senator from Colorado, his state's first Hispanic senator, a man of Mexican descent who served as Biden's ambassador, saying plainly that the administration's border posture was a political and policy failure.

The word they refused to say

Salazar wrote that inside the Biden administration, officials used the word "crisis" constantly when discussing the border. The problem was not ignorance. It was messaging discipline, or, more accurately, messaging cowardice.

The White House refused to acknowledge the situation as a crisis publicly, even as its own people described it that way behind closed doors. Salazar said he advised then-Homeland Security Secretary Alejandro Mayorkas to use the word openly. Mayorkas, according to Salazar, declined with a revealing answer:

"Ken, I have a lot on my plate already. I'm about to be impeached for all this border stuff. The Republicans have it out for me."

That exchange captures the administration's posture in miniature. The concern was not the crisis itself, it was the political fallout from naming it. Mayorkas was more worried about his own impeachment proceedings than about leveling with the American public.

Salazar's early advice to Biden was blunt: call the border situation a crisis and act accordingly. The White House ignored him. The result, as Salazar himself put it, was a "political failure to understand the reality of the crisis at the border, and the political consequence it would have on Democrats in the 2024 election."

Harris and the hollow title

Salazar had pushed the Biden White House to create a border czar position. When Kamala Harris was assigned to address the "root causes" of migration, Salazar initially saw it as progress. What followed was, by his own account, nothing.

"But sadly, her designation in this position was having no effect on migration flows."

He continued: Harris "had been placed in charge of getting at the 'root causes' of migration, but many felt she had been ineffective." Then he delivered the sharpest line in the book excerpt: "For whatever reason, she had been unable to help with the border and migration crisis, even though she'd sat next door to the Oval Office for almost four years."

That is not a Republican talking point. That is the former U.S. ambassador to Mexico, a Democrat, a Biden appointee, saying the vice president failed at the one border-related task she was given. The criticism is all the more striking because Salazar wanted the czar role to exist. He got what he asked for. What he did not get was results.

The broader record of Harris's public standing since leaving office has only reinforced the impression that the border portfolio became an anchor she could never shake.

A primary challenge that almost was

After Biden's disastrous July 2024 debate performance, Salazar told himself: "I should run for president." He was not merely venting. He recruited a team. He drafted a platform. He prepared to throw his name into the ring if Biden stepped aside.

Biden's debate collapse has become a contested chapter in Democratic history. Former Biden insiders have disputed the family's version of events surrounding that night, and Salazar's account adds another voice to the chorus of Democrats who saw the debate as a turning point, not just for Biden's candidacy, but for the party's credibility.

When Biden finally dropped out, Salazar expected the party to hold open primaries. Instead, Democrats consolidated behind Harris without a competitive process. Salazar called that decision "a mistake."

The speed of that consolidation has been well documented. Harris pushed for Biden's endorsement within minutes of his withdrawal, according to Jill Biden's own memoir. The party's rank and file never got a say. Salazar, who had been preparing to offer an alternative, was shut out before he could begin.

Too little, too late

Salazar praised Biden's eventual decision to effectively shut down the border in 2024. But he acknowledged what every honest observer already knew: it came far too late to matter.

"This should have been a moment of vindication, after all, American voters were demanding action on the border, but it was too late, and images of an out-of-control border would dominate the closing months of the presidential election."

That sentence is a concession that the border issue decided the 2024 election, and that Democrats lost it because they spent years refusing to act. Salazar is not blaming Fox News or Republican messaging. He is blaming his own party's leadership for ignoring a crisis that voters could see with their own eyes.

The broader question of whether Biden's inner circle shielded him from hard truths, about the border, about his own fitness, has only grown louder. Jill Biden has claimed no aide warned her about the president's health before the debate, a claim that strains belief given the number of insiders who have since spoken up.

Salazar's next play

The former ambassador is not retreating into retirement. He has already met with Arizona Democratic Sens. Mark Kelly and Ruben Gallego, and plans to sit down with Illinois Gov. JB Pritzker, Politico reported. He is pitching what he calls his "borderlands platform", an immigration policy framework built on the premise that the U.S. immigration system is broken and "must be fixed."

That Salazar feels the need to make this case to his own party tells you where Democrats still stand on the issue. Three years of record illegal border crossings, a lost presidential election, and an insider's book-length rebuke later, the party's leading figures apparently still need to be tutored on why the border matters to voters.

Fox News Digital contacted Salazar, Pritzker, Gallego, and Kelly for comment. The medical and political fallout from Biden's debate collapse continues to produce new disclosures, and Salazar's book promises to be another chapter in the ongoing reckoning.

The lesson Democrats still won't learn

Salazar's account is useful precisely because it cannot be dismissed as partisan. He served Biden. He wanted the administration to succeed. He watched it fail on the border anyway, not because the problem was unsolvable, but because the people in charge refused to name it, staff it, or fix it until voters had already made up their minds.

The ambassador begged for a czar. He got one who did nothing. He urged the White House to say "crisis." They wouldn't. He prepared to run against his own president. The party wouldn't let anyone run at all.

When your own ambassador starts drafting a primary challenge over the border, the problem was never the messaging. It was the policy, and the people who chose politics over reality until reality chose for them.
