Kennedys sue to block Trump's arch, arguing it would cast shadow on JFK's grave

Last week the project won approval from the National Capital Planning Commission.

But US District Judge Tanya Chutkan then ruled there should be a 14-day pause before any work can start on the arch as litigation plays out.

The Kennedy family filed its complaint under a joint lawsuit brought by the state of Virginia and Washington DC seeking to block construction, arguing that the arch will damage "historically significant sightlines" if erected at the gateway of the cemetery.

The plaintiffs include seven children of Robert and Ethel Kennedy, as well as their grandson - former Democrat congressman Joe Kennedy - and Ted Kennedy's son Edward Kennedy Jr.
