David Friedman, an adviser to Donald Trump, visited Israel and met with senior officials of the government, according to Haaretz, an Israel-based newspaper.
Israeli Prime Minister Benjamin Netanyahu reportedly dispatched advisers to meet with representatives of Hillary Clinton's campaign in the U.S. at the same time, so as not to appear to be meddling in the American election.
Friedman's visit to Jerusalem also included a meeting with members of "Republicans Overseas" as part of an effort to get out the vote for Trump in Israel.
According to polling of Israel from earlier this summer reported by the Jerusalem Post, Israelis appear almost evenly divided about whether Trump or Clinton would make a better president, with Clinton having a slight edge.
If the Trump-Clinton race becomes competitive, American Jews could become a crucial voting bloc in several likely swing states. Israel is also of importance to evangelical Christian voters.
