If this story is true, I must push back on our President just a bit because per his usual he's being a touch hyperbolic. And the very smart people he surrounds himself with will be realistic on this flagpole & flag size thing.
According to the NY Post, he has suggested an "almost 100-foot-tall American flag". That would require a flagpole of somewhere in the neighborhood of 500 feet tall. A 3ftx5ft flag is standard size, and it requires a pole of at least 15 feet above ground. The general rule is that a flagpole needs to be at least 5 times the vertical length of a flag.
I'd modestly suggest an array of three flagpoles wherever on the White House grounds he prefers. A 60 footer in the center for the American Flag, and a pair of 50's on each side. One with the POW-MIA flag on permanent display, and the other for special occasions, such as a visiting delegation from a foreign land.
And for the DUmmies who are deriding a gold flagpole...it wouldn't be pure gold you ****-tards. An anodized gold is incredibly classy and popular.
Long story why I know all this....
