Merz's forthright, "shoot-from-the-hip" style of politics could add an interesting dimension to the meeting. His remarks can be surprising and make headlines - a stark contrast to those of his more cautious predecessors, Olaf Scholz and Angela Merkel.Though a traditional supporter of transatlantic relations, Merz raised eyebrows in February by declaring the current US administration is "indifferent to the fate of Europe".
So far, the White House has been uncharacteristically quiet about Merz's visit.It was only briefly mentioned by Press Secretary Karoline Leavitt in a gaggle with reporters on Monday, and not at all during briefings at the White House and State Department on Tuesday.Sources familiar with the visit suggested several topics that could dominate the conversation.

They have names on them that make wine lovers go weak at the knees - Nuits-Saint-Georges, Echezeaux, Vosne-Romanée, Clos-Vougeot, and Chapelle-Chambertin.Ms Tremblay sells over half of her wine abroad, under the name Domaine Cecile Tremblay.
