FORMER senator Panfilo Lacson on Tuesday slammed former president Rodrigo Duterte's demeanor and 'invasion' of the Senate blue ribbon subcommittee investigation on his alleged bloody war on drugs.

The come-backing senator, in a statement, criticized what he perceived was a 'disrespectful takeover' of the Senate public hearing on the Duterte administration's controversial war on drugs. He condemned Duterte's demeanor during the drug war probe on Monday conducted by the Senate blue ribbon subcommittee led by Senate Minority Leader Aquilino Pimentel III.
