Gotchu!
Sen. Tim Scott(R) ran for President this year, but Presidents need a First Lady. Tim Scott, however, is a lifelong bachelor and an alleged penis connoisseur.
Since Republicans would NEVER nominate a gay man, Sen. Scott allegedly hired an actress to play the role of his girlfriend and help him dispel the gay rumors.
After Tim Scott dropped out of the primaries, he tried to position himself to be Trump's running mate. Since that didn't work out, Scott no longer needed his fake girlfriend.
