The Guardian:
A German diplomat has criticised a group of Bundestag MPs over their behaviour on a recent visit to San Francisco, accusing them of using a racial slur and of choosing sightseeing and shopping above meetings with US counterparts. Rolf Schütte, the German consul general in San Francisco, wrote to the foreign ministry in Berlin to express his outrage. His confidential letter, which is furious and frank in tone, has been leaked to the German press and created a public debate about the legitimacy of publicly funded foreign political trips and whether they should be more tightly controlled.
One of several articles in the German press: Die Welt: USA-Dienstreise wird für Politiker zur Blamage
Correction of the Guardian article: Not a member of parliament, but a parliamentary staffer is accused of the racial slur.
