Refers to this New Republic article, describing when Brooks first met Obama in 2005:

That first encounter is still vivid in Brooks’s mind. “I remember distinctly an image of--we were sitting on his couches, and I was looking at his pant leg and his perfectly creased pant,” Brooks says, “and I’m thinking, a) he’s going to be president and b) he’ll be a very good president.”

"That first encounter is still vivid in Brooks’s mind. “I remember distinctly an image of--we were sitting on his couches, and I was looking at his pant leg and his perfectly creased pant,” Brooks says, “and I’m thinking, a) he’s going to be president and b) he’ll be a very good president.”

Brooks was probably staring at Obama's crotch, not the crease in his pants.
