Did president Taft approve the 16Th and 17Th amendment?

Yes, President William Howard Taft supported both the 16th and 17th Amendments. The 16th Amendment, ratified in 1913, allowed Congress to levy an income tax, which Taft endorsed as a means to generate revenue. The 17th Amendment, also ratified in 1913, established the direct election of U.S. senators, a reform Taft favored to increase democratic accountability in government.
