Story highlights Donald Trump has offered conflicting opinions about Angela Merkel

The GOP nominee alternatively praised and criticized the German chancellor

(CNN) Asked to name a world leader he admires and would like to emulate, Donald Trump on Thursday pointed to the foreign head of state he has most vigorously criticized on the campaign trail.

Trump has repeatedly vilified Merkel for accepting an influx of Syrian refugees into her country, saying she is "ruining Germany." His criticism of Merkel began last December when Time magazine named Merkel person of the year over Trump.
