DANIEL GREENFIELD: How Hamas Bought Joe Biden.

But the single most shocking document from James Biden’s relationship with Qatar may be a letter that he allegedly wrote to the Qatari leadership on “behalf of the Biden family.”

“We are not particularly close to this administration and have a different vision,” Biden’s brother wrote, accusing the Trump administration of being “fractured” and “beleaguered by major issues that are not soon to be resolved.” However he promised that the Biden “family could provide a wealth of introductions and business opportunities at the highest levels that I believe would be worthy of the interest of His Excellency.”

“If this is in keeping with the vision of His Excellency, on behalf of the Biden family, I welcome your interest here,” he concluded.

Even while undermining the sitting administration, Biden’s brother was offering the services of his family to an enemy nation. This has wider implications beyond Qatar’s role backing Hamas.

Qatar was also the central intermediary in the Taliban “deal” and had formed an alliance with Iran. It is difficult to know whether the “Biden family” relationship with Qatar played any role in the disastrous withdrawal from Afghanistan and in the sanctions relief offered to Iran.

We do know there was a relationship between the Biden family and a state sponsor of Hamas, which Joe Biden profited from, and that has disturbing implications for our national security.

“We’ve got people all around the world who want to invest in Joe Biden,” James Biden once bragged. One of those investors had ties to Iran, Al Qaeda, Iran and Hamas.
