en.wikipedia.org/wiki/Keiko_Fujimori

This claim gives the wrong year for Pedro Pablo Kuczynski's resignation.

Reliable contemporaneous reporting shows that:

• Kuczynski offered his resignation on March 21, 2018 amid the Odebrecht-related political crisis.
• Peru's Congress accepted the resignation on March 23, 2018, after which Martín Vizcarra was sworn in.

So the article's date of 23 March 2017 is incorrect; the relevant events happened in March 2018.

The article says Keiko Fujimori headed the Fundación por los Niños del Perú from April 1994. But contemporaneous and retrospective reporting places her assumption of that role after she became first lady in August 1994.

• El Comercio reports that Alberto Fujimori removed Susana Higuchi as first lady on 23 August 1994, and that from Keiko Fujimori's appointment onward she was also president of the association/foundation for Peru's children.
• Revista Ideele, quoting official reporting from El Peruano, says Keiko Fujimori was incorporated as president of the foundation in mid-August 1995.

These sources differ on the exact later date, but both contradict the claim that she led the foundation starting in April 1994. That month is too early.
