(CNN) The House Judiciary Committee moved Tuesday to authorize subpoenas for two separate issues: an array of documents and testimony related to the administration's immigration policies and to former and current Trump administration officials, including the President's son-in-law Jared Kushner, as part of its probe into potential obstruction of justice.

The committee is planning a Thursday vote to authorize the subpoenas, which would ratchet up the Democrat-led panel's investigation into possible obstruction of justice and examination of the Trump administration's immigration policies. The vote would allow Judiciary Chairman Jerry Nadler, a Democrat from New York, to issue the subpoenas at his discretion.

The committee has previously requested numerous documents related to immigration matters from the administration, but Tuesday's notice to authorize subpoenas is an escalation of those requests. It shows the committee is broadening the investigation into President Donald Trump as Democrats weigh whether to start an impeachment inquiry and comes ahead of former special counsel Robert Mueller's testimony before the House Judiciary and Intelligence Committees next week.

Over recent months, Democratic lawmakers have grilled administration officials in congressional hearings on the "zero-tolerance" policy that led to the separation last year of migrant families who crossed the southern border illegally, and most recently, have expressed ongoing frustration over conditions at border facilities amid an influx of migrants at the US-Mexico border.
