Handling of classified documents, Hunter's laptop, intelligence agencies using social media for domestic propaganda, the politicization of the justice department, foreign influence... All that stuff.
And the charge levied against them is gonna be that they're wasting all their time on these hearings rather than using it to govern, but that's nonsense.
If they pass any legislation to address the unsustainability of entitlements rapidly approaching insolvency before it becomes too late, that legislation will never get through a Democrat Senate.
If they pass any legislation to address our massive military overreach (at least in ways that don't put "American First" if that's the GOP standard), it ain't gonna pass a Senate intent on keeping open a blank check to Ukraine, right or wrong.
If they pass legislation to improve American education by ending the department, it's dead on arrival in the upper chamber and seen as extreme.
Like... They might be able to make some improvements to veterans affairs or infrastructure, name a post office or two... But hearings and investigations is all they really can do with the Democrats holding the Senate and the Presidency. So it's sorta hard to blame them for playing the hand they have.
