They sent the FBI after Trump for "secret documents" because of an informant and played it for months. Many on the Left/Demmies talking heads, politicians wanted Trump arrested and put away for treason.
However, when classified documents were found at multiple times and in multiple places; at an office the Biden used at the Penn Biden Center, a University of Pennsylvania-affiliated think tank in Washington, and at Biden’s home.

But when GOP and other people pressed for answers, the WH accused GOP of playing politics to smeared Biden - kinda like how the GOP was supposedly smearing Biden over the Hunter Biden laptop, Biden having a Ukranian investigator/lawyer fired for digging into it, etc etc.
“House Republicans are playing politics in a shamelessly hypocritical attempt to attack President Biden,” White House spokesman Ian SamsIlhan Omar (one of the Demmie young Sqaw):
Investigations Into Biden Classified Document Scandal Are A ‘Political Game’.So, according to Lefties/Demmies, investigation into one of their own is "political game" or "playing politics" but it's insurrection/treason for the other group
