Marjorie Taylor Greene will serve on at least two committees, including one that oversees national security. Here's what to expect.

• Rep. Marjorie Taylor Greene is expected to serve on the Homeland Security and Oversight Committees.
• She'll be taking part in investigations of the Biden administration and overseeing national security.

After two years in Congress without a seat on any House panels, Republican Rep. Marjorie Taylor Greene of Georgia is set to serve on two major committees: the House Committee on Oversight and Accountability and the House Committee on Homeland Security

The House GOP Steering Committee voted unanimously on Tuesday to recommend that she serve on the two committees. The entire House Republican conference votes to ratify committee recommendations, which they are expected to do.

In a statement on Tuesday, she said the Oversight panel "could arguably be the most important committee" of the 118th Congress.

"Joe Biden, be prepared," she said. "We are going to uncover every corrupt business dealing, every foreign entanglement, every abuse of power, and every check cut for The Big Guy."

Of the Homeland Security Committee, she said Republicans would "investigate the Biden administration's violations of our laws."

While all members of Congress typically get committee seats, the House voted to strip Greene of her committee assignments in February 2021 over her history of promoting conspiracy theories and political violence.

But since then, she's become a major power player on the right, raising millions of dollars while campaigning for candidates aligned with former President Donald Trump in the 2022 midterm election. House Speaker Kevin McCarthy has also courted her support, and she became a vocal proponent of his speakership bid after previously expressing doubts.

The Homeland Security Committee, set to be chaired by Republican Rep. Mark Greene of Tennessee, deals with national security issues including border security, counterterrorism, election security, and cybersecurity.

It also oversees the Department of Homeland Security, a federal agency created in the wake of the September 11 attacks. Greene has called for the impeachment of the agency's current leader, Secretary Alejandro Mayorkas.

The Oversight committee, set to chaired by Republican Rep. James Comer of Kentucky, is the House's main investigative panel and is set to be the springboard for a slew of investigations that Republicans are planning targeting the Biden administration.

Here's what to watch for as Greene takes her seat on committees.

Renewed calls for Mayorkas's impeachment

Greene is one several Republicans who has called for DHS Secretary Alejandro Mayorkas to be impeached over Republicans' disagreement with President Joe Biden's policies on border security and immigration.

She even co-sponsored a resolution from Republican Rep. Pat Fallon of Texas, introduced last week, that would impeach Mayorkas.

As Insider reported last week, Mayorkas is a major target by House Republicans. If successful, it would be the first time since the 1800s that a Cabinet secretary has been impeached.

Greene and other Republicans could seek to use hearings on border security and immigration enforcement as an avenue to make their case for impeachment.

Made-for-TV moments

While Greene once dismissed committees as a waste of time, her exclusion from high-profile congressional hearings has deprived her of a key opportunity for politicians seeking the spotlight.

Members of Congress from both parties come to hearings with well-rehearsed lines of questioning for witnesses, often with the goal of scoring political points or proving a point rather than soliciting new information.

The committee's hearings, which typically take place on a near-weekly basis, are likely to offer Greene a new avenue through which to promote her views.

Possible promotion of election-related conspiracy theories

One area of jurisdiction for the Homeland Security committee is election security, and Greene still hasn't relented in her false claim that the 2020 election was stolen from Trump.

Under Democratic control, the committee held hearings on threats to election officials and voters' confidence in election infrastructure. Under Republicans, it's possible the focus will turn more towards claims of election and voter fraud.

As a member of the committee, Greene could use her time on the dias to promote claims that the 2020 election — as well as other recent elections Democrats have won — were stolen.
