Donald Trump delivered a blistering rebuke of Hillary Clinton on Wednesday, attacking her actions as President Obama's secretary of state and what she did as a U.S. senator and first lady.

"She lacks the temperament, the judgment and the competence to lead our country. She should not be president under any circumstances," the presumptive GOP nominee said in a speech at Trump SoHo in New York.

Trump slammed Clinton for making millions of dollars giving speeches to Wall Street banks and special interest groups after she left the White House in 2001, and claimed that the financial sector will "totally own her" if she is elected president. Clinton has refused to release the transcripts of those speeches, but she has claimed she never made promises to any of them.

"She's doesn't have the temperament, or, as Bernie Sanders said very strongly, the judgment to be president. She does not have the judgment," Trump said.

He blasted Clinton's support for the North American Free Trade Agreement (NAFTA) signed in the mid-1990s under President Bill Clinton, calling it "among the most destructive agreements we ever signed." He also criticized Clinton for walking back her support of the Trans-Pacific Partnership trade agreement.

Trump claimed that Clinton "deleted at least 30,000 emails" from her time as secretary of State when she ran her own private email server and that the government should recover them. He claimed that foreign entities have her deleted emails and that they now have a "blackmail file" over Clinton.

"This is the latest Clinton cover-up and it doesn't change anything," Trump said.

Clinton has vehemently denied deleting any emails from her tenure at the State Department and has said she supports the release of her emails to the public.

Trump said the world was different before Clinton took over as secretary of State in 2009. He said that before Clinton was appointed Iraq was seeing a reduction in violence, Syria was calm and the Islamic State in Iraq and Syria (ISIS) didn't exist.

"Fast forward to 2013: In just four years, Secretary Clinton managed to almost single-handedly destabilize the entire Middle East," Trump said. "Her decisions spread death, destruction and terrorism everywhere she touched."

He also brought up her role during the Benghazi attack, and claimed that Ambassador Chris Stevens was "left helpless to die as Hillary Clinton soundly slept in her bed."

Trump also condemned Clinton's support for the Iraq War and claimed that he opposed the invasion from the beginning. Six months before the March 2003 invasion, however, Trump indicated in an interview with Howard Stern that he supported invading Iraq.

Trump said he would appoint judges who uphold the Constitution, and would, in his first 100 days, change immigration rules, end regulations that help send jobs overseas, repeal and replace Obamacare and pass "massive tax reform to create millions of new jobs."

Clinton campaign spokesman Glen Caplin said that Trump is only rehashing and recycling "more tired and old nonsense from books that have already been debunked."

"This is more distraction from a candidate that cannot answer or dispute any of yesterday's criticism of his business record, his economic policy or the dangers he would pose to working families. Rather than coherently defend his record or his plans, Trump will instead resort to peddling yet more discredited attacks from his 'look over there' campaign playbook," he said.
