WASHINGTON — On a recent trip to Washington for a research symposium, Michelle Beermann veered into a nearby gift shop, drawn by the prospect of adding to her new bust collection.

The 24-year-old stood in front of the display in White House Gifts, carefully weighing the faux bronze and marble options — Presidents John F. Kennedy and Barack Obama among them — before choosing a bust of Abraham Lincoln, her favorite president, to join the ranks of William Shakespeare, George Washington and various figures of Greek mythology in her home.

And while Ms. Beermann, a student at the University of Illinois, plans to eventually add those two other presidents to her collection, she is adamant that a bust of President Trump will not be among them.

“I’m just not a fan of his, for political reasons,” Ms. Beermann said. “I didn’t want him staring at me.”
