The U.S. Justice Department has sought the removal of a judge president over the case on President Donald Trump's deportation of Venezuelans, a court filing showed on Monday.

The Trump administration on Monday repeatedly stonewalled a federal judge seeking answers about whether the government had violated his order barring the deportation of more than 200 noncitizens without due process, escalating a conflict that threatened to become a constitutional crisis.

President Donald Trump also said he planned on Tuesday to speak with Russian President Vladimir Putin, as the U.S. president seeks to find a common ground for a potential ceasefire between the Kremlin and Kyiv.
