From the seeded article:

The trip of US Republican presidential hopeful Mitt Romney to Israel is in bad taste for lots of reasons.

1. He is holding a fundraiser at the King David Hotel in Jerusalem. It is distasteful for an American political candidate to hold a high-profile fundraiser abroad, implying a commitment to a foreign country as a means of reaching out to American interest groups (in Romney's case, Christian Zionists among the evangelicals and the minority of American Jews who would be willing to vote Republican). 

2. Romney has broken his pledge of transparency and declared the fundraiser off limits to the US press.

3. Romney won't explain why he has abruptly gone back on his word, and closed the Jerusalem event to the press.

4. There is a convention in US politics that you don't criticise the sitting president, even if you are an opposition politician, while on foreign soil. Romney clearly intends to slam Barack Obama while in Israel.

5. Romney is clearly holding the event in some large part to please casino mogul Sheldon Adelson, who first bankrolled Newt Gingrich and now is talking about giving $100m to elect Romney. Adelson is a huge supporter of rightwing Likud party prime minister Binyamin Netanyahu, and published a free newspaper in Israel to support all things Bibi all the time. Adelson is under investigation on suspicion of bribing Chinese officials in Macau in reference to his casino empire there. Since Adelson is potentially an agent of Chinese influence and is a partisan of one of Israel's most rightwing parties, Romney's indebtedness to him is disturbing.
