An attorney directed particular ire toward the New Hampshire-based company, C&S Wholesale Grocers, which would acquire 579 stores sold off by the grocer after they combined.

The third trial attempting to stop the $25 billion deal to merge Kroger and Albertsons began Monday in Colorado.

The third trial challenging the proposed Kroger, Albertsons merger began Monday in a Denver district court, but the case differs from separate lawsuits brought by the Federal Trade Commission and the Washington attorney general as it seeks $1 million each in civil penalties from the two grocers.

After two weeks of legal arguments and testimony the hearing on Kroger's proposed $25 billion takeover of Albertsons is getting closer to wrapping up.

The trial for the case brought forth by Colorado against the parent companies who run King Soopers and Safeway stores across the state will begin on Monday — marking the start of the third trial attempting to block the proposed $25 billion deal.

On Monday, the CEOs for Kroger and Albertsons were pushed, and pushed back, over whether the two grocery retailers need to merge.

Kroger will face off with regulators over its embattled proposed merger with Albertsons – this time against Colorado Attorney General Phil Weiser.
