Where Katz stands

Federal spending and inflation: Says federal spending drives inflation. Pledges to work with President Trump to stop wasteful federal spending and to require accountability in the federal budget.
Taxes: Opposes raising taxes on working families. Supports making pro-growth tax cuts permanent and cutting back federal regulation.
Energy: Supports a diversified energy strategy that includes nuclear power, and backs the ADVANCE Act on permitting and advanced nuclear technology. Says federal decisions on offshore wind and the grid should not raise Delaware families' costs.
Housing: Proposes removing federal barriers to home construction and creating tax incentives, lending standards and construction support for first-time homebuyers. Also proposes zoning reform partnerships to add affordable housing.
Health care: Supports prescription drug pricing reform that protects innovation, more rural health funding for Kent and Sussex counties, lower insurance premiums, and making mental health part of primary care.
Military and veterans: Supports fully funding military readiness and modernizing the armed forces. Also supports protecting veterans' benefits, reducing VA disability claim backlogs and expanding telehealth for rural veterans.
Campaign priorities: Says his focus in the Senate would be lowering the cost of living, fixing the health care system and making the federal government more fiscally responsible.
