It's fair to assign the blame for actions of the executive branch of the US government to Trump while he holds the office of president. The policy of sanctioning people for being too critical of Israel required his assent whether or not he made the call to apply it in this case or delegated that to a subordinate.

Especially problematic is that her actions would be unambiguously protected speech under US law if she did them in the USA.
