Members of the House Oversight Committee will receive a classified briefing next week on unidentified anomalous phenomena (UAP), better known as UFOs, Axios has learned.

Why it matters: Congressional interest in the issue has grown in recent years, with a small but vocal group of lawmakers in both parties pushing for greater transparency from the government on the issue.

Driving the news: The members-only briefing will be held in the Office of House Security on Jan. 12, according to two sources familiar with the matter and a notice viewed by Axios.

• The briefing is being provided by the Office of Inspector General of the Intelligence Community, the notice said.

The backdrop: A bipartisan group of Oversight Committee members led by Rep. Tim Burchett (R-Tenn.) sent a letter to intel community inspector general Thomas Monheim in August requesting more details about UFOs, including any programs to reverse engineer them or retrieve crashed UFOs.

• The letter was in response to testimony the previous month from former intelligence official David Grusch, who claimed the government was in possession of "nonhuman biologics" from a recovered UFO.
• The lawmakers also formed a Congressional UAP Caucus, consisting of Burchett and Reps. Jared Moskowitz (D-Fla.), Anna Paulina Luna (R-Fla.), Nancy Mace (R-S.C.), Eric Burlison (R-Mo.) and Andy Ogles (R-Tenn.).

What they're saying: "I just want transparency," Burchett told Axios in a statement. "We've got a lot of questions ... If we are paying millions of dollars to investigate them, we should be able to see the results."
