Department of the Taoiseach

All records of correspondence between the Taoiseach/Department of an Taoiseach and the White House between the dates of January 1, 2019 to May 21, 2019. The records I am seeking are letters/emails any other form of recorded correspondence sent to the White House in any capacity by either the Taoiseach or the Department. In addition to that I'm seeking any records of correspondence in response from the White House itself that the Department of an Taoiseach is in possession of.
