Israel bars Democratic congresswomen from entering country - CNNPolitics
"The boycott movement, formally known as the Boycott, Divest, and Sanctions movement, aims to end international support for Israel because of its policies towards Palestinians, as well as its continued construction of West Bank settlements, considered a violation of international law.
Tlaib and Omar have been vocal critics of Israel and have supported the boycott movement, also known as BDS, and voted against a House resolution condemning the BDS movement, which received broad bipartisan support.
Israel passed a law in March 2017 which allows the country to bar entry to anyone who supports the BDS movement. The controversial law, passed by Israel's right-wing and centrist parties, was roundly criticized by human rights organizations. If used to deny entry to Tlaib and Omar, it would be by far the most high-profile implementation of the law."
