For me it would be Diamine Oxblood ink (only ink I have). And the Lamy Safari EF I got a year ago thanks to the Mr. Bingle exchange.
I do not see how a president can be forced to use multiple pens or any specific brand for anything. If I was signing a bill it would be MY pen that goes back into MY pocket and it would be my Sheaffer Imperial (1961) that I inherited from my late father. Ink would be Noodler's Black or Parker Quink. I would hand out as many gov't issue pens as required but none would actually be used to sign any legislation. For other correspondence, I would use a Lamy Safari until a US maker could provide an equivalent pen.
