Tim Walz, Kamala Harris' vice-presidential candidate, has Luxembourgish roots. His great-great-grandfather, Nicolas Reiser, was born in Kehlen, Luxembourg and this connection makes Walz part Luxembourgish. 

Indeed, Tim Walz's maternal lineage traces back to Luxembourg. His great-great-grandfather, Nicolas Reiser, was born in Kehlen in 1836, according to Luxroots, the Genealogy Center of Luxembourg. Reiser moved to the United States at the age of 18 but returned to Luxembourg to marry Susanne Pütz from Septfontaines. The couple then emigrated back to the US, where they had 12 children, including John Francis Reiser who is Walz’s great-grandfather.

John Francis Reiser, together with Barbara Lucy Engelhaupt, had Mary Helen Reiser, who is Tim Walz’s grandmother. Mary Helen Reiser’s daughter, Darleen Rose Walz, married James Frederick Walz, and they had Timothy James Walz in Nebraska.

This makes the US Vice-Presidential candidate approximately 12.5% Luxembourgish! Additionally, Walz has German, Swedish, and Irish ancestry, according to EthniCelebs.com.
