As we noted yesterday, conservative Catholic activist Joseph Cella, a member of Donald Trump’s new Catholic advisory committee and reportedly the new “chief liaison to the campaign for Catholic affairs,” joined other Catholic conservatives earlier this year in denouncing Trump as “manifestly unfit to be president of the United States.”

Cella appeared on Ave Maria radio yesterday afternoon and told host Al Kresta that he is now “happily” supporting Trump. When Kresta asked what had changed since the “manifestly unfit” statement, Cella said he has had a “sincere change of heart and mind.” Trump, he said, had convened some Catholic leaders in June to “listen and learn.” He said Catholic voters are coalescing around Trump and predicted that trend will continue.

Cella praised Trump’s public commitment to nominating conservative Supreme Court justices in the mold of the “great Catholic jurist and thinker” Antonin Scalia. Clinton, he said, would do the opposite, and with the next president likely having the opportunity to fill three to five vacancies, “that alone will have far-reaching and long-lasting implications for the Catholic Church” on issues like religious liberty and health care.

Cella also mentioned Trump’s naming of Religious Right favorite Mike Pence to be his running mate and his “excellent” senior staff—he said the Trump campaign’s top three leaders are Catholic.
