Really, you want to prevent some US Congresswomen from visiting Israel? In democracies, people criticize as they invoke free speech. Your closest among the few allies is the US. What if the Democrats win the Presidency, keep the House and also win the Senate and then choose to pass some restrictive laws that might prevent people like you from visiting US? Don’t take things for granted because you are in power now supported by someone else in power in the US. Things can change.
