WASHINGTON (AP) — House Republicans have launched an effort to expand the massive tax law they muscled through Congress last year, aiming to make permanent the individual tax cuts and small-business income deductions now set to expire in 2026.

The push before the midterm elections, which clicked into gear Tuesday, is portrayed as championing the middle class and small businesses. Rep. Kevin Brady, R-Texas, who heads the tax-writing House Ways and Means Committee, said making the tax cuts permanent would build on the tax law’s economic boost by adding 1.5 million new jobs and increasing wages.

With the elections about four months away, polls are showing mixed support among voters for the $1.5 trillion package of individual and corporate tax cuts that President Donald Trump signed into law as his marquee legislative achievement.
