A Democratic lawmaker wore a Hillary Clinton campaign pin during a congressional oversight hearing about the FBI probe regarding the presidential candidate's private email server.

Rep. Sheila Jackson Lee, a Democrat representing Texas, raised quite a few eyebrows Wednesday when she sported the gold 'H' letter campaign pin to a House Judiciary Committee hearing.

FBI Director James Comey testified to the committee on the agency's decision not to charge Clinton.

Jackson Lee, who wore a red suit jacked that had a silk scarf draped over her shoulders that did not block the campaign pin, questioned Comey during the hearing.

'[Republicans] want you to prosecute, or ask the DOJ to prosecute, Secretary Clinton regardless of the facts,' she told Comey, while wearing Clinton's campaign pin.

'So they've engaged in an almost daily ritual of holding hearings, desperately trying to tear down the investigation.'

Comey, 55, also discussed the set of controversial immunity deals that were given to members of Clinton's staff.

Despite the House having guidelines that restrict certain forms of campaign-related activity, there are no apparent bans on wearing campaign pins for presidential candidates. Jackson Lee and Clinton are pictured above in 2008

Despite the House having guidelines that restrict certain forms of campaign-related activity, there are no apparent bans on wearing campaign pins for presidential candidates.

This isn't the first time Jackson Lee, 66, has been spotted wearing the pin.

She wore the gold 'H' during the vote to override President Barack Obama's veto of a bill that would allow September 11 victims' families to sue Saudi Arabia.

In addition, Clinton's vice presidential running mate, Sen. Tim Kaine, arrived on the Senate floor wearing a 'H' lapel pin.
