Conservative magazine The Weekly Standard is closing down after 23 years.

The publisher, Clarity Media Group, is citing fewer subscribers as the reason. The Weekly Standard was often critical of President Donald Trump.

Founded by Bill Kristol and Fred Barnes and backed by media mogul Rupert Murdoch’s News Corp. in 1995, it was acquired by Clarity Media Group in 2009.

Clarity Media President and CEO Ryan McKibben said in a statement that the magazine had double-digit declines in its subscriber base all but one year since 2013.

Denver-based Clarity also owns the Washington Examiner magazine, weekly magazine Colorado Politics and daily newspaper Colorado Springs Gazette.
