Earlier today President Biden made a rare appearance since dropping out of the presidential race, and it was to announce a prisoner swap with Russia, including some American citizens who will be returning home:

In one of the largest prisoner swaps between the United States, its allies and Russia since the end of the Cold War, Wall Street Journal reporter Evan Gershkovich and former U.S. Marine Paul Whelan are among more than a dozen prisoners released by Russia in exchange for Russian prisoners held by the United States and countries throughout Europe, U.S. officials said Thursday.

In all, under the deal, 16 political prisoners, journalists and others, including five Germans, are being exchanged for eight Russians jailed in the U.S., Germany, Norway, Slovenia and Poland. Among the Russians is Vadim Krasikov, a convicted Russian state assassin in German custody, as well as three other Russians in U.S. custody.

[...]

Those returning to the U.S. from Russia include Gershkovich, Whelan, Russian American journalist Alsu Kurmasheva, who works for U.S.-funded Radio Free Europe, and Russian journalist and dissident Vladimir Kara-Murza, a U.S. permanent resident.

At the end of his remarks, Biden was asked about Donald Trump saying that he would have been able to get the prisoners freed without giving up anything in exchange.

The lefty media won't be in a hurry to do a thorough fact-check on Biden's response, which was to answer a question with a question: 

Predictably, libs think that was a mic drop from Biden. But let's pursue Biden's question, which was "why didn't Trump do it when he was president?" 

To a large degree there's a good reason that didn't happen:

A lot of "reporters" won't want to interfere with the Left's "mic drop moment from Biden" by delving too deeply into the details.

It's a safe bet the MSM will not make the details about all this the lead part of the story when reporting about Biden's remark.
