GUATEMALA CITY (AP) — Guatemalan lawmakers have voted for a second time in two weeks against stripping President Jimmy Morales of his immunity so that prosecutors could pursue a campaign finance investigation.

This time the votes in favor of lifting his immunity reached 70, 45 more than the last vote, but still well short of the 105 required.

The vote followed massive street protests calling for the resignation of Morales and legislators.

The government said in a statement Thursday that the vote should be understood within the context of the separation of powers.

Prosecutors say they found $825,000 of hidden expenditures and additional unexplained financing from Morales' 2015 campaign.

Last month, Guatemala's chief prosecutor and the U.N. anti-corruption commission chief requested that Morales' immunity be lifted. Morales then tried to expel the commission's chief.
