Harris played a key role in arranging the prisoner swap

The Wall Street Journal:

Harris’s meeting with Scholz was particularly critical to securing the exchange because releasing Krasikov was a key Russian demand. The two first had a normal bilateral meeting before Harris asked Scholz to stay back for a “restricted bilateral,” the official said. Harris asked everyone to leave except Scholz and one aide on each side.

“They had a back and forth about how to best move forward about that, but ultimately, she was pressing Scholz to take action on this,” the official said.

Harris has met Scholz previously on several occasions and had a “good working relationship with him,” the official said. That is “part of the reason why she was able to have a really good, frank conversation with him.”

And Biden, once again putting country above self-interest, was working on the deal right before he announced he was withdrawing as a presidential candidate. 

Notable detail: Just an hour before Pres. Biden announced he was exiting the 2024 race last month, he was on the phone with his Slovenian counterpart, "urging them to make the final arrangements" for this massive prisoner swap, according to a senior administration official.

Another accomplishment to add to Biden’s legacy

A legacy that will shame anyone who disapproves of his presidency.
