GOP Delegate Update, Trump-Sanders Campaign In NY, Hillary Takes Heat From Sanders

A resounding win in Colorado's GOP contest this weekend provided fresh evidence that Donald Trump's campaign is still scrambling to catch up in the state-by-state delegate hunt.

But the Trump campaign's threat that they might challenge the Colorado results at the Republican National Convention showed something else: Their campaign is gearing up for battle in Cleveland -- and no error will go unnoticed.

The debate over the national delegate selection in Colorado this weekend qualified as the very definition of inside baseball.

But that is the game that the GOP campaigns will be playing at the convention if no candidate reaches the 1,237 delegates needed to clinch the nomination before Cleveland.

The cell that carried out the Paris and Brussels attacks sought to target the Euro 2016 soccer championships in France, ISIS terror suspect Mohamed Abrini has told interrogators, according to a source close to the investigation.

Investigators are working to verify Abrini's claims, the source told CNN.

Also, a computer used by Brussels attackers Ibrahim and Khalid El Bakraoui and found in a garbage bin outside the group's bomb factory contained a file of research indicating La Defense shopping mall in Paris and a Catholic association were additional potential targets, the source said.

The Euro 2016 tournament, slated to run from June 10 to July 10 in cities across France, is one of the biggest international sports spectacles in the world.
