FYI, the plan is not to expand the U.S. economy, but to contract it. GDP is not a completely good measure to measure the U.S. economy with. In fact, a high GDP might not mean that the economy is better off, but worse off. This is because GDP measures the price of which products are sold, and not the quantity. This means high inflation. Inflation was sky-high since the pandemic.
During the pandemic inflation was artificially caused in order to combat the recession. GDP raised, but the not the quantity of goods sold, but the price was raised. This is done by pushing production past its potential. In an economy, production cannot go past a certain point that is determined by a nation's technology. This point is known as the the production potential, or the long run aggregate supply curve (LRAS). If production is pushed past this point, then the price of goods raise, but quantity does not raise. At this point the national supply curve is vertical, asymptote, and only the price of goods will rise, not the quantity. This was done on purpose to raise prices and fight the predicted recession from the pandemic. Now that we are in a conservative administration, the plan has changed.
Conservatives believe in contractionary policies, lowering prices and inflation. In order to fight inflation, GDP must be lowered below the LRAS potential point. There is an economic concept called the Phillip's Curve, and this curve says that as unemployment rises, inflation falls. As inflation falls so do prices. Raising taxes (tariffs) and cutting government spending are all ways to lower production, and inflation. Consumer spending must also stop. These economical laws and theories are very paradoxical, but in the long run are for the best.
Here is a graph showing how GDP within the last 5 years has been artificially raised by pushing production past its potential in order to raise prices. More products were not produced, but the price was raised, which means higher GDP. This is not exactly good for the economy. It is a technique to combat recession.
Data comes from the U.S. Bureau of Economic Analysis.

Here is the concept of the LRAS curve, and how it becomes vertical. If production is pushed along the vertical curve, then only prices will raise, but quantity will not. Quantity is measured on the horizontal axis, and price is measured on the vertical axis of the graphs. LRAS is the long run aggregate supply curve, and AD is the aggregate demand curve for a whole nation.
