On Tuesday, the House Judiciary Committee issued subpoenas against Hope Hicks and Annie Donaldson, both alumni of President Donald Trump‘s administration. In total, the committee has requested documents and testimony from 81 individuals with connections to Trump.

Hicks and Donaldson are requested to hand over documents to the House Judiciary Committee by June 4, and both women are requested to testify later in the month. Hicks, one of Trump’s former advisors and confidants, is slated to appear before the committee on June 19, while former White House deputy counsel Donaldson is scheduled for June 24.

The House Judiciary Committee’s latest subpoenas come during a period of heightened friction between Trump and House Democrats; Trump recently said he has no intention of cooperating with Democrats so long as their investigations into him are ongoing. It is likely the White House will attempt to prevent both women from complying with the committee’s subpoenas, having successfully prevented ex-White House counsel Don McGahn from testifying before the Judiciary Committee.

SLIDESHOW: TOP DEMOCRATS RUNNING FOR PRESIDENT IN 2020

Trump and his associates are currently accusing Democrats of attempting a “do-over” of special counsel Robert Mueller‘s probe. While Mueller’s report painted Trump in a bad light, it lacked enough evidence to charge anyone in his inner circle of colluding with Russia. Nevertheless, accounts that have been given by Donaldson and McGahn depict Trump’s anxious mindset during Mueller’s investigation, and both Hicks and Donaldson were depicted as two individuals of note within his report.

“Is this the beginning of the end?” Donaldson asked on May 9, 2017. According to Mueller’s findings, “she was worried that the decision to terminate [former FBI director James Comey] and the manner in which it was carried out would be the end of the presidency.”

Aside from its subpoenas for Hicks, Donaldson and McGahn, the committee has also subpoenaed the Justice Department for a copy of the full, unredacted Mueller report.
