Rudy has to be physically present in the Capitol for the House to effect an arrest. Otherwise the arrest warrant has to be executed by the DoJ Marshal Service. Holder was found in contempt but obviously DoJ would not execute any Congressional order. So as long as Rudy et al refuse to show up any arrest order is meaningless.
If he decides to show he can respond “I do not recall.” or invoke 5th amendment and force an immunity grant, followed by “I do not recall”
I did not know all that. Thank you.
