Former Rep. Lincoln Diaz-Balart returned to Capitol Hill on Thursday, but not in his capacity as chairman of the Congressional Hispanic Leadership Institute, or for any business connected to his Miami-based consulting firm.

The Florida Republican who retired from the House in 2010, instead, came to testify at an Energy and Commerce subcommittee hearing “to examine federal efforts on suicide prevention.”

Diaz-Balart — whose brother, Rep. Mario-Diaz-Balart, R-Fla., still serves in office — appeared before the panel to speak, for the first time in public, about the May 2013 suicide of his son, Lincoln Gabriel, who was then 29-years-old.
