[Answer] Who was the last U.S. President that sported facial hair while in office?

Step 1 : Introduction to the question "Who was the last U.S. President that sported facial hair while in office?"

...It’s been more than a century since a US president had facial hair. The last time facial hair graced the face of a US president was March 4, 1913. This was the day William Howard Taft and his voluminous mustache were replaced by the clean-shaven Woodrow Wilson in the nation’s highest office. The American Mustache Institute suggests March 4th be known as “Taft Day” in remembrance. Abraham Lincoln started the trend in 1861, when he entered office as the first president with a beard or mustache—only sideburns had previously appeared in the White House. From 1861 to 1913, nine of eleven US presidents had facial hair.
