GOP presidential candidate Bill Weld is calling on President Trump to resign from office in the wake of Robert Mueller’s investigation, calling him “a one-man crime wave,” the Boston Globe reports.

Weld, writing for The Bulwark: “How can a president function if he instinctively lies to not only the public but to his own staff? There is one essential truth that leaps from the pages of the Mueller report: No one can trust Donald Trump.”

Former Massachusetts Governor William Weld said he planned to challenge President Trump for the 2020 Republican presidential nomination, Reuters reports.

Said Weld: “In these times of great political strife, when both major parties are entrenched in their ‘win at all cost’ battles, the voices of the American people are being ignored and our nation is suffering. It is time for patriotic men and women across our great nation to stand and plant a flag.”

Former Gov. Bill Weld (R) “announced his presidential exploratory bid last month with a flourish, capturing headlines by calling Donald Trump ‘a schoolyard bully’ and dismissing Washington Republicans for exhibiting ‘all the symptoms of Stockholm syndrome,’” Politico reports.

“Then he went dark. Aside from a few television hits and public appearances, the former Massachusetts governor has done little to suggest his primary election challenge to Trump is something the president needs to worry about.”

Former Massachusetts Gov. William Weld is launching a presidential exploratory committee to challenge President Trump in the Republican primaries, saying the country is “in grave peril” and he “cannot sit quietly on the sidelines any longer,” the Boston Herald reports.

“Weld becomes the first Republican to officially announce he is exploring a run against Trump, and sets up a potential match-up in the first-in-the-nation New Hampshire presidential primary and in other states.”

Former Massachusetts Gov. William Weld has changed his party registration from Libertarian back to Republican as he mulls a possible primary challenge against President Trump, the AP reports.

Weld served as a Republican governor from 1991 until 1997. He later became a Libertarian and ran for vice president on a ticket with former New Mexico Gov. Gary Johnson in the 2016 election.

Former Gov. William Weld, who was the Libertarian Party’s nominee for vice president in 2016, is mulling a run for president and could make an announcement about a possible presidential run in the next few weeks, WCVB reports.

He would run as a Republican. The news makes Weld the first who could create a primary challenge for President Donald Trump in 2020.

Matt Lewis: “Weld may be the ice-breaker, but he’s a perennial candidate whose fealty to the Republican Party is suspect, having defended Hillary Clinton while running as the Libertarian Party V.P. candidate in 2016. His value will likely be making it easier for others to take the primary plunge.”
