Well, President Trump has fired a new salvo in his battle to stop migrants crossing the southern border. He's now calling for a 5 percent tariff on all goods from Mexico starting June 10, unless the Mexican government stems the tide of families and children coming from Central America.

The president's plan sparked concern today from both immigration activists and business groups. We will get the details after the news summary.

The watchdog agency for the Department of Homeland Security is warning of dangerous overcrowding at migrant detention sites. Today's report says federal inspectors in El Paso, Texas, found 900 people in facilities designed for a maximum of 125. Some were held in standing-room-only conditions for days.

Others reportedly stood on toilets to gain breathing space. The report warns the health and safety of both detainees and border agents are at risk.

In a new interview, Attorney General William Barr says he doesn't think senior FBI officials committed treason when they investigated the Trump campaign. President Trump has repeatedly claimed there was treason.

But Barr disagreed when speaking with CBS' Jan Crawford.
