Your asking the question as a statement.
However, Nobody should be complaining about Old Man Biden using rails either but the hypocritical bullshit that they made up about Trump was usually fake.
Whereas this with Biden is real and done because he really is frail and does need the rail combined with hunching his back to get up the stairs, but they don't report the facts of his appearance or actions accurately. Biden should use rails if he needs to as should have Trump if required. Do you recall they even had Trump as scared of stairs.
Note the Tags on this meme, if the press acted to Biden like they did with Trump
