Vatican spokesman Greg Burke and his deputy abruptly resign

The Pope, flanked by Greg Burke, answers questions from journalists in January 2018.

(CNN)Vatican spokesman Greg Burke and his deputy, Paloma Garcia Ovejero, have resigned, an official Vatican statement announced Monday.

The statement confirmed that Pope Francis accepted their resignations but did not provide more details about their abrupt exit.
Burke, an American, tweeted Monday that he and Ovejero, a Spaniard, had resigned effective January 1.
"At this time of transition in Vatican communications, we think it's best the Holy Father is completely free to assemble a new team," Burke said.
    The former Fox News journalist, who joined the Vatican in 2012, described his experience as "fascinating, to say the least."
    Francis appointed Alessandro Gisotti, a member of the Vatican's communications office, as interim director of the Holy See Press Office.
    Their departure comes several weeks after Francis appointed Italian journalist Andrea Tornielli as editorial director of all Vatican media and Andrea Monda as editor of the Vatican newspaper, marking a significant shake up of the Vatican's media operations.
