Shameless pandering.
Congress first designated it by public law in 1991. Both Republican and Democrat administrations have issued the proclamation each year (18) since.
This is in addition to
Black History Month – February – 1926
Asian/Pacific American Heritage Month – May – 1977
Hispanic Heritage Month – September – 1968
American Indian/Alaska Native Heritage Month – November – 1990
Sounds fake to me

BTW, Obama's ancestor Fulmuth Kearney from Moneygall, Co. Offaly emigrated to America in 1850 at the age of 19. A shoemaker by trade, he settled in Ohio as a farmer.
