Official Confirmation: Trump Aide Natalie Harp Worked at White House Without Clearance

Then lede paragraph:

Ein vertrauliches Schreiben des Weißen Hauses, das dieser Redaktion vorliegt, belegt, dass Natalie Harp, ehemalige politische Assistentin von Donald Trump, seit Anfang 2023 ohne behördliche Sicherheitsfreigabe im Westflügel arbeitet.
