UPDATE 1-Argentina's Macri chooses moderate Peronist as VP candidate

Moderate Peronist Senator Miguel Pichetto will run as vice president under Argentine President Mauricio Macri in October elections, the president wrote on Twitter on Tuesday, a selection that could help broaden the leader's voting base.

In a series of tweets, Macri called the October election an opportunity to "consolidate democracy" and laid out a series of goals such as defending human rights and combating crime. "For all of this, we'll need to build agreements with a lot of generosity and patriotism, which all Argentines that share these values can support," Marci wrote.

"Because of all of this, I want to announce that Miguel Angel Pichetto will accompany me as vice-presidential candidate."
