The transit system for the nation's capital region is pulling ads promoting a new book by right-wing provocateur Milo Yiannopoulos.

The Washington Post reports Metro is removing the ads after finding that they violate the system's guidelines.

Yiannopoulos is self-publishing the book, "Dangerous," after publisher Simon and Schuster canceled his book deal.

The cancellation came after a backlash to recorded remarks in which Yiannopoulos seemed to defend sexual relationships between men and boys.
