Democratic Senator Richard Blumenthal has broken with his party by acknowledging that Republican concerns over alleged Justice Department surveillance of lawmakers during Jack Smith's investigations are legitimate, in a rare bipartisan moment amid an escalating Capitol Hill row. The dispute centres on newly released documents that Senate Republicans say show serious misconduct by the former special counsel, who led federal probes into Donald Trump, raising broader questions about the propriety of using DOJ powers to monitor members of Congress.

Blumenthal, a Connecticut Democrat, told Fox News Digital that his Republican colleagues are right to be troubled by reports that the DOJ spied on lawmakers to assist Smith's investigations, while adding that more facts are needed before drawing final conclusions. The controversy has intensified political tensions in Washington as Republicans push for further scrutiny of Smith's conduct, with the episode being seen as a notable instance of a senior Democrat breaking ranks on an issue usually split along strict party lines.
