Lawmakers will miss a hearing on law enforcement access to data on Wednesday, after Senate Democrats moved to slow down proceedings over President Trump’s Tuesday firing of FBI Director James Comey.

Members of a Senate Judiciary subcommittee were due to examine law enforcement’s access to electronic data stored outside the United States Wednesday afternoon.

“Due to the Democrats obstructing normal business in the Senate, I have been forced to postpone this afternoon’s Crime and Terrorism Subcommittee hearing,” Graham said in a statement.

Earlier Wednesday, Democrats invoked a procedural tactic that limited the time and length of committee meetings in response to Trump’s abrupt removal of Comey Tuesday evening. The firing, which came as Comey lead the FBI investigation into potential ties between Trump's campaign and Russia, has prompted outcry among Democrats and concerns from some Republicans.

The hearing on police access to data was planned to feature two witness panels. Richard Downing, acting deputy assistant attorney general at the Department of Justice, and Paddy McGuinness, a deputy national security advisor for the British government, had been scheduled for the first panel.

The senators also would have heard from a panel that included the president and chief legal officer of Microsoft, the director of a digital evidence laboratory in the office of Massachusetts’ attorney general and a professor at American University’s law school.

Graham did not announce when the hearing would be rescheduled.
