Obama signed the extensions while he was in France. I can imagine the old timers complaining that the “founding fathers” did not intend for the POTUS to sign laws via autopen:
Look at the relevant section of Article I, Section 7:
Every Bill which shall have passed the House of Representatives and the Senate, shall, before it become a Law, be presented to the President of the United States; If he approve he shall sign it, but if not he shall return it, with his Objections to that House in which it shall have originated,
Was the bill “presented” to the President? Well, according to the media reports he reviewed it so most likely a copy was transmitted to him in Europe.
Did he “sign” it? Is signing via electronic device from thousands of miles away what the Founders had in mind? Probably not, but they probably also didn’t have ball point pens in mind either. It isn’t the means of signing that’s the issue but the manner and, in this case, the cause for concern should be that at a document is “signed” by the President without him actually being in the room, or the country. It may be Constitutional, but I hope they turn the machine off at night so someone isn’t granting pardons under the rug.
