Metro Manila (CNN Philippines) — Even before the "main event" between Davao City Mayor Rodrigo Duterte and Sen. Antonio Trillanes IV takes place on Monday (May 2), Sen. Grace Poe has a piece of advice for her closest rival.

"Para rin sa sarili niyang kapakanan, mas maigi na na ilabas, 'di ba, kasi kung wala naman talagang… Kung hindi naman kanya 'yon, e, di ilabas na lang na hindi kanya 'yon, mas makakatulong pa sa kanya," said Poe.

[Translation: For his own beneift, it is high time to dislose, right, because if there is really nothing... If the accounts are not his, then it should be clarified, something that can be of help to him.]

Poe said she has been in Duterte's place, where there have been a lot of questions thrown at her, specially on her qualifications.

The lawmaker pointed out she presented everything — all the documents — to the Supreme Court.

"Hangga't maaari, 'yung aking mga dokumento pinakita ko para mawala na 'yung isyu. Ganoon din siguro para sa isang katulad niya na marami ngayon dapat talagang pabulaanan," Poe said.

[Translation: As much as possible, I showed my documents to put an end to the issue. Same goes for him, given that he has a lot to account for now.]

Poe's running mate, Sen. Francis "Chiz" Escudero, agrees.

"Naniniwala ako kandidato ka man o hindi, ano mang katanungan dapat sagutin, ano mang isyu kailangan ipaliwanag," said Escudero.

[Translation: Whether candidate or not, I believe one has to answer questions that must be answered, issues that must be explained.]

On Duterte's changing statements, Poe said the public should be assured that their president will always tell the truth.

"Hindi pwede talagang ngayon ganito, bukas iba. Paano na lang tayo makakaasa?" Poe quipped.

[Translation: Now it's like this, tomorrow it's different — that cannot be the case. How can we hope for something?]

No more room for complacency

Meanwhile, Poe said there is no word yet from the Iglesia ni Cristo (INC) as to who it will endorse.

On the latest Pulse Asia presidential survey, Poe admitted there is a lot more to be done and there is no room for complacency.

"Ako'y naniniwala sa survey. Kaya nga, para sa akin, hindi ko sinusuko ang laban sapagkat ito'y isang paraan para maialay ang sarili kung anong maitutulong ko sa ating mga kababayan," said Poe.

[Translation: I have faith in the suvey. That's why, for me, I won't give up the fight as this is my way of offering myself to help our countrymen.]

But when asked for reaction now that she is statistically tied with Mar Roxas, Poe had this to say.

"Ay, okay. Thank you. Thank you. Thanks guys," as Poe walks out of the frame.
