The Jan. 6 select committee is pushing back at a challenge to its legitimacy, citing a probe House Speaker Nancy Pelosi, D-Calif., once derided, Politico is reporting.

In a late-night court filing, House Counsel Douglas Letter defended the Democrat-controlled select panel against claims it is invalid since Republican leaders have not appointed any of its members.

Letter pointed to the formation in 2005 of a select committee, which was set up to investigate the government response to Hurricane Katrina.

That panel was made up of 11 Republicans appointed by then-Speaker Dennis Hastert.

Pelosi had objected to the committee and called it a partisan “sham," according to Politico.

Letter’s defense of the Jan. 6 panel came in a case involving Taylor Budowich, a spokesman for former President Donald Trump. Budowich wants the committee to return his bank records, which it obtained last month from JPMorgan Chase. He maintains the Jan. 6 panel is structurally flawed.
