### Legislation and tenure

Duncan was a "Tea Party freshman" in the 112th Congress.
In February 2011, Duncan introduced a resolution to create a new committee on the elimination of nonessential federal programs in an attempt to reduce federal outlays.
On January 18, 2012, Duncan introduced the Countering Iran in the Western Hemisphere Act of 2012 (H.R. 3783). This bill made it U.S. policy to use a comprehensive strategy to counter Iran's growing hostile presence in the Western Hemisphere by working together with U.S. allies and partners in the region to deter threats to U.S. interests by Iran, the Iranian Islamic Revolutionary Guard Corps (IRGC), the IRGC's Qods Force, and Hezbollah. On December 28, 2012, President Barack Obama signed the act into law.
On November 19, 2012, Duncan wrote Obama a letter discouraging him from nominating Susan Rice as secretary of state. His letter, which was signed by 97 members of Congress, stated that Rice "either willfully or incompetently misled the American public in the Benghazi matter" and that she had lost the American people's trust and would greatly undermine U.S. credibility abroad.
On April 18, 2013, Duncan introduced the Outer Continental Shelf Transboundary Hydrocarbon Agreements Authorization Act (H.R. 1613). This bill approves a year-old agreement between the U.S. and Mexico to allow the joint development of oil and gas straddling the two countries' maritime boundary in the Gulf of Mexico. H.R. 1613 passed the House with bipartisan support on June 27, 2013. It was subsequently wrapped into the Continuing Resolution of December 12, 2013.
On January 16, 2014, Duncan introduced the Energy Exploration and Production to Achieve National Demand Act (EXPAND Act) (H.R. 3895). The act frees Americans to produce more energy in the U.S. from all sources.
On March 13, 2014, Duncan introduced the DHS Acquisition Accountability and Efficiency Act (H.R. 4228; 113th Congress), a bill that directed the United States Department of Homeland Security to improve the accountability, transparency, and efficiency of its major acquisition programs. The bill specified procedures for DHS to follow if it failed to meet timelines, cost estimates, or other performance parameters for these programs. Duncan argued, "for years, DHS's purchases of major homeland security systems have been late, cost more, and done less than promised. This bill will save taxpayer dollars by forcing DHS to improve its management."
On February 23, 2016, Duncan introduced H.Res. 617, which gave the House the authority to file suit against the Obama administration should it violate or attempt to violate the law regarding the transfer of detainees from the detention facility at Guantanamo Bay.
In January 2017, Duncan introduced in the House the Hearing Protection Act of 2017 (HPA) (H.R. 367), which would reclassify gun suppressors (silencers) from Title II weapons to Title I weapons (currently ordinary shotguns, rifles and handguns, weapons "not regulated by the National Firearms Act, but regulated by the Gun Control Act of 1968 and other federal laws"), restricting their regulation and making them easier to buy. The HPA amends the Internal Revenue Code and Title 18 of the United States Code to eliminate the transfer tax and paperwork associated with registration of suppressors, refund the tax to anyone who paid it after October 22, 2015 (the date the first Hearing Protection Act was introduced, by Matt Salmon), and "preempt" existing state or local silencer taxes and regulations. In June 2017 Duncan added the HPA to the wide-ranging Sportsmen Heritage and Recreational Enhancement (SHARE) Act, of which he was also the lead sponsor.
On January 19, 2018, Duncan introduced the Ultrasound Informed Consent Act (H.R. 4844), which ensures that women seeking an abortion receive an ultrasound and the opportunity to review it before giving informed consent to receive an abortion.

## Political positions

Duncan has described himself as "a strong advocate for life and traditional family values".
In the House chamber, Duncan wore a mask reading "Let's Go Brandon", a popular coded message in Republican circles for an obscene insult to Joe Biden.

### Abortion

Duncan is firmly opposed to abortion and exceptions for rape, incest, or saving the life of the mother. He has cosponsored legislation to ban late-term abortions, to end federal funding for abortion providers like Planned Parenthood, and to protect conscience rights for businesses and health care professionals who oppose paying for or participating in abortions.

### 2nd Amendment

Duncan believes that all Americans have the right to own firearms. In addition to introducing the Hearing Protection Act, he has co-sponsored bills to expand concealed carry reciprocity rights. Duncan has been endorsed by the NRA Political Victory Fund, who gave him an "A" rating in 2014, rising to an "A+" by 2020.

### LGBT rights

In 2015, Duncan cosponsored a Congressional resolution to amend the Constitution to ban same-sex marriage.

### Taxes

Duncan voted for the Tax Cuts and Jobs Act of 2017. He has also cosponsored legislation to repeal the income tax, the estate tax, the health insurance tax, and the entirety of the tax code.

### Health care

Duncan supported the full repeal of the Affordable Care Act, voting on numerous occasions to repeal it in full or in part. He supports replacing the ACA with free-market solutions, having cosponsored legislation to expand health savings accounts, make all health care spending tax-deductible, supporting Christian charity health plans, and creating association health plans.

### Immigration

Duncan opposes amnesty for illegal immigrants. He believes border security is a constitutional responsibility of the federal government. Duncan supports the construction of a border wall with physical fencing, surveillance technology, and increased border patrol agents on the ground. In February 2017, he introduced the Terrorist Deportation Act (H.R. 844), which makes it harder for suspected terrorists to come to the U.S. and easier to remove those already here. Duncan is also a co-sponsor of "Goodlatte/McCaul", H.R. 4760, which requires mandatory E-verify, makes it a crime to overstay a visa, eliminates chain migration, ends the diversity lottery, and creates an agricultural worker visa program.
Duncan voted against the Fairness for High-Skilled Immigrants Act of 2019 which would amend the Immigration and Nationality Act to eliminate the per-country numerical limitation for employment-based immigrants, to increase the per-country numerical limitation for family-sponsored immigrants, and for other purposes.
Duncan voted against the Further Consolidated Appropriations Act of 2020 which authorizes DHS to nearly double the available H-2B visas for the remainder of FY 2020.
Duncan voted against the Consolidated Appropriations Act (H.R. 1158), which effectively prohibits Immigration and Customs Enforcement from cooperating with the Department of Health and Human Services to detain or remove illegal alien sponsors of Unaccompanied Alien Children.

### Energy

Duncan supports increased use of fossil fuels. He sponsored the legislation to implement the Transboundary Hydrocarbon Agreement with Mexico, and cosponsored legislation supporting offshore energy exploration, seismic testing, clean coal technology, nuclear power production, and the export of natural gas. Duncan has also worked to ease regulations on hydraulic fracturing, coal ash, the social cost of carbon, and the "Waters of the United States" regulation. He supported the Department of Interior and Bureau of Ocean Energy Management's January 2018 decision to allow more access to the Outer Continental Shelf.
In December 2023, Duncan introduced the Atomic Energy Advancement Act, provisions of which were passed as part of the ADVANCE Act within the Fire Grants and Safety Act, which was signed into law by President Joe Biden in July 2024.

### Foreign policy

In 2019, Duncan signed a letter led by Representative Ro Khanna and Senator Rand Paul to President Trump. The letter asserted that it is "long past time to rein in the use of force that goes beyond congressional authorization" and that they hoped this would "serve as a model for ending hostilities in the future—in particular, as you and your administration seek a political solution to our involvement in Afghanistan."
In 2019, Duncan was one of 60 representatives to vote against condemning Trump's withdrawal from Syria.
In 2020, Duncan voted against the National Defense Authorization Act of 2021, which would prevent the president from withdrawing soldiers from Afghanistan without congressional approval.
In July 2021, Duncan voted against the bipartisan ALLIES Act, which would increase by 8,000 the number of special immigrant visas for Afghan allies of the U.S. military during its invasion of Afghanistan, while also reducing some application requirements that caused long application backlogs; the bill passed in the House 407–16.
Duncan voted to provide Israel with support following 2023 Hamas attack on Israel.

### Texas v. Pennsylvania

In December 2020, Duncan was one of 126 Republican members of the House of Representatives to sign an amicus brief in support of Texas v. Pennsylvania, a lawsuit filed at the United States Supreme Court contesting the results of the 2020 presidential election, in which Joe Biden defeated Trump. The Supreme Court declined to hear the case on the basis that Texas lacked standing under Article III of the Constitution to challenge the results of an election held by another state.

### Support for impeaching President Joe Biden and Alejandro Mayorkas

During the 117th United States Congress, Duncan was co-sponsor of three resolutions to impeach President Joe Biden and one resolution to impeach Secretary of Homeland Security Alejandro Mayorkas.

### MLB

Duncan was the lead sponsor of a bill to remove Major League Baseball's antitrust law exemption after the league pulled its 2021 All-Star Game from Atlanta in protest of Georgia's new voting law.
