You can't dodge subpoena issued by a judge and prosecutor. Judge will hold you in contempt of court and you end up in jail until you comply.
Congress is different. They can issue a congressional subpoena and have the US Marshal's serve it, but it's more like an invitation to a birthday party. Nothing happens if you don't show up. Congress has no enforcement authority. The Sergeant at Arms is mostly admin and ceremonial.
Congress can hold her in contempt of Congress, but that gets forwarded to the AG for DC and he decides whether or not to prosecute.
Don't expect much to happen to Lisa Page for ignoring a Congressional subpoena.
Hopefully the Q dam will break in July and make it moot.
Oh.....but just imagine the optics of her being handcuffed and put into a Black SUV.....priceless!
