MANILA, Philippines — House prosecutors expressed confidence on Sunday that the Senate impeachment court would vote in favor of their request to subpoena Vice President Sara Duterte’s financial records, saying the documents are crucial to determining whether she amassed unexplained wealth and betrayed the public trust.

The vote, set for Monday afternoon, is expected to be one of the most consequential procedural rulings in Duterte’s impeachment trial, now on its seventh day, with prosecutors arguing the records are essential to proving allegations under Article II of the articles of impeachment regarding her undeclared wealth.

The proposed subpoena covers Duterte’s bank accounts, tax records and documents from the Anti-Money Laundering Council (AMLC), as well as those of her husband, lawyer Manases Carpio.
