Regardless of what Biden said in his January 6 speech against Trump and the events of January 6, 2021, what he failed to say, and when his press conference was scheduled, is much more significant. The article behind this LINK lays it out quite distinctly.
“The principle that governs national presidential addresses is to avoid saying what must not be said. The purpose of the speech was not to expose the truth of what took place on January 6, 2021, but to deflect and obfuscate.
The real truth can only be extracted by reviewing what Biden did not say.
First, Biden’s speech did not explain why, if the country is under the imminent threat of dictatorship, his administration delayed giving this speech for an entire year.”
