ROME, July 6 (Reuters) - Italy's defence minister stressed the importance of good transatlantic relations on Monday after U.S. President Donald Trump again goaded erstwhile ally Giorgia Meloni, the Italian prime minister. Meloni last month accused Trump of fabricating a story about her after the U.S. president told an Italian TV channel that she had "begged" him to take a photo with her at a G7 summit in France.
