Republican presidential candidate and former Arkansas Gov. Mike Huckabee said on Monday that President Obama’s administration is “the most anti-Christian in American history,” according to The Iowa Statesman.

Huckabee was upset over Obama inviting transgender activists and the first openly gay Episcopal bishop to the welcoming ceremony for the pope at the White House. The Vatican criticized the invitations and said that photographs of the pope and these individuals might suggest approval of their decisions, according to the Wall Street Journal.

Huckabee called Obama’s decision a “politicized cattle call” in his statement.

“President Obama’s classless decision to transform Pope Francis’ visit to the White House into a politicized cattle call for gay and pro-abortion activists is an insult to millions of Catholics,” according to the statement. “Why is it that Obama goes to extremes to accommodate Muslim terrorists but shows nothing but disdain for Christians? This is a new low for an administration that will go down as the most anti-Christian in American history.”
