You can film them, just not obstruct with them executing their official duties.

Personally, I'd wait another 3 years to visit until this brainless ass clown is out of office (or maybe 10 years later after our society recovers a bit from completely melting down because we have a civil war when said ass clown refuses to peacefully leave office and the large number of ass clown citizens back him up because they are afraid to truly live freely)

I make this recommendation as a very reluctant republican (who proudly has never voted for president ass clown).

This question is from 2015.
