CHANGE: Trump shakes up campaign, demotes top adviser.

Stephen Bannon, a former banker who runs the influential conservative outlet Breitbart News and is known for his fiercely anti-establishment politics, has been named the Trump campaign’s chief executive. Kellyanne Conway, a veteran Republican pollster who has been close to Trump for years, will assume the role of campaign manager.

Two Trump campaign aides confirmed the staff’s reshuffle early Wednesday, requesting anonymity to discuss personnel changes without permission.

The campaign also announced that “the first major TV ad buy of the general election [is] slated to start later this week.”
