Four years in, President Donald Trump has plenty of unfinished business

President Donald Trump swept into office nearly four years ago as an outsider who promised to get things done quickly on behalf of American people through sheer force of will and unrivalled kwledge about art of deal.

He has checked off some items on his to-do list.

Trump pushed through most significant overhaul of U.S. tax system since President Ronald Reagan. Trump, as he said he would, tilted Supreme Court furr to right with confirmation of two conservative justices and likely a third, Amy Coney Barrett, in coming days. His promise to get tough on illegal immigration has resulted in a surge in migrant apprehensions at U.S.-Mexico border.

But Trump has also faced same hard truth that each of his White House predecessors learned: Governing is rarely easy.

A look at some of president's unfinished business as he asks voters for a second term in White House:

Health Care

Trump has mand to undermine President Barack Obama's health care law but has fallen far short of his promise to repeal and replace Affordable Care Act.

His administration has mand to dismantle parts of law. Enrollment periods have been shortened, some subsidies were ended and individual mandate -- fine for people without health insurance -- has been eliminated.

Trump says he's still focused on replacing with something much better and much less expensive. He said in an interview with CBS' 60 Minutes that it will be so good if Supreme Court puts an end to Obamacare when justices hear challenges to it next month.

number of uninsured Americans has risen under Trump's watch.

According to Census Bureau data released last month, nearly 30 million people in U.S. lacked cover at some point during 2019, about 1 million more than in previous year.

Endless wars

Trump has made only modest progress toward meeting his 2016 pledge to bring home all troops from what he calls America's endless wars. When Trump took over White House, number of U.S. forces in Afghanistan stood at about 8,400, and re were about 6,800 troops in Iraq.

Within a year, number of troops in Afghanistan climbed to about 15,000.

Trump approved commanders' requests for additional troops to reverse setbacks in training of Afghan forces, fight an increasingly dangerous Islamic State group and put eugh pressure on Taliban to force it to peace table.

In February, U.S. and Taliban signed an agreement that calls for eventual complete withdrawal of U.S. forces from Afghanistan.

With an eye toward election, Trump has accelerated his push to bring troops home, teasing that all U.S. troops could be out of Afghanistan by end of year.

Pentagon officials said number of troops in Afghanistan will drop to 4,500 in vember. But defense officials insist re are plans to have all troops home from Afghanistan by end of year. U.S. officials also say re currently is approved plan to reduce number to 2,500 by early next year. officials were t authorized to publicly discuss internal deliberations and spoke on condition of anymity.

In Iraq, number of U.S. troops has dipped from about 5,000 to roughly 3,000, although officials say number fluctuates higher as units rotate in and out.

wall

During his 2016 primary run, Trump sought to mark his ground as a hard-line immigration enforcer who would build a great, great wall on our sourn border.

And I will make Mexico pay for that wall, Trump said as he launched his run for White House in June 2015. Mark my words. Nearly four years later, Trump still has work to do completing his wall and much that has been completed has been paid by U.S. taxpayers despite promises orwise.

president's administration has promised to build 450 miles by end of this year and has so far built 371. Trump has replaced hundreds of miles of old, worn-out barriers, meant only to stop cars, with tall, 30-foot fencing that is much harder to get over and impedes wildlife from crossing border. Conservationists in Arizona, where a bulk of building has taken place, say new wall is detrimental to wildlife and surrounding ecosystems.

Mexico has steadfastly refused to pay for border wall, though Trump earlier this year suggested that wall is being paid, in part, by remittances from Mexican immigrants working in U.S.

To date, money is coming from U.S. Treasury, meaning today's taxpayers and future ones who will inherit federal debt. To extent any people who came into U.S. illegally are kicking in for wall, it's because y're working and paying taxes like or workers.

Trump also freed up 3.6 billion for wall last year by diverting money from military construction projects as well as 2.5 billion from approved counterdrug spending.

Mideast peace

Early in his presidency, Trump expressed confidence that his administration could broker a long-term peace agreement between Israel and Palestinians.

We will get it done, Trump declared in May 2017. He put his son-in-law and senior adviser Jared Kushner in charge.

Trump moved U.S. Embassy in Israel from Tel Aviv to Jerusalem, a step that was cheered by Israelis and president's evangelical Christian supporters in U.S. but angered Palestinian leaders.
