President Biden passively fumed about the southern border crisis as it began to receive media attention in the early months of his presidency, a new book claims.

Chris Whipple, author of The Fight of His Life: Inside Joe Biden’s White House, alleges that Biden was so upset that staffers heard him "dropping f-bombs" like a sailor.

Biden's border secret

The president received the most sustained scrutiny over the border during a brief period in March of 2021, which appears to be the period the book is referencing.

"Illegal immigrants kept arriving. And Biden was furious,” Whipple writes. "From all over the West Wing, you could hear the president cursing, dropping f-bombs (he’d always apologize when women were present)."

Whipple also writes that the border is the only issue besides COVID vaccine "disinformation" that makes Biden's "blood boil."

“Early in his term he had reserved the f-bomb mostly for discussions of the southern border, but lately he was using it more often,” Whipple wrote.

No "solutions?"

According to Whipple, Biden was angry about a lack of "solutions," apparently unaware that his own relaxed policies and messaging were behind the surge.

“It was just the frustration of a lack of solutions,” a senior adviser said, according to Whipple. “It’s like, ‘how would you feel if you were me and these were the solutions you had?’ It’s the weight of the presidency, right?”

The story rings true based on Biden's well-known tendency to snap in public, irritability being one of the symptoms of dementia.

But if Biden was privately angry about the border, that emotion has not been reflected in any public urgency at the White House to address the problem.

Biden's self-pity

Two years into his presidency, Biden is still claiming, preposterously, that the border is "secure" as an unprecedented human tsunami threatens to overwhelm the system.

It has been to Biden's benefit that the media have been largely uninterested in covering the crisis, which Biden has sought to blame on distant "root causes" in Latin America and a "broken system" Biden says he inherited.

Biden's self-pity is remarkable considering the burden the crisis is imposing on American citizens, especially those living in border communities.

In the past two years since Biden was inaugurated, more than 4 million illegal immigrants have crossed the border, a record surge that is expected to get worse if Biden succeeds in ending President Trump's Title 42 policy. The Supreme Court moved last month to keep the policy in place, for now.
