ICE outrage in Maine today A young man was needlessly and senselessly shot and killed. The ICE agents involved and their supervisors must be held accountable. ICE should be dismantled and only reconstituted if part of a larger, just, and comprehensive immigration reform package. #MEpolitics

MDP's requirements for US Senate candidates to qualify for its nominating convention on July 25. 500 signatures from Maine Democrats submitted by Tuesday, July 21 (50 signatures from no fewer than eight counties). Interested in helping? Let us know at campaign@costelloforsenate.com #MEpolitics

Suggestion: use ME’s ranked choice voting to determine G. Platner’s replacement. The simplest, least time-consuming way to involve the most voters (June primary 220,000+) in the process and guard against the Party’s nominee being chosen via a low-turnout caucus or by Party leaders #MEpolitics

Brief statement regarding Maine’s US Senate race to replace Susan Collins: I’m back in, if Graham Platner withdraws. For more information on my reform ideas and why I believe I’m the best candidate to defeat Sen. Collins, check out my earlier social media posts and website at costelloforsenate.com

It’s well past time we mended a broken Washington. Before Trump it was endless gridlock. Since Trump, it’s been increasing chaos, incompetence, and corruption. To fix Washington, let’s start by replacing “concerned” senators like Susan Collins with REAL CHANGE reform advocates like me! #MEpolitics

Virtual Town Hall - Please join us this evening at 7:00 PM for another virtual town hall with David. We’d love to have you participate. If interested, you can RSVP at: www.costelloforsenate.com/event-detail...

LET’S DEBATE!!! Maine’s US Senate race is not settled and appears to be tightening. ME’s primary election is next week and there’s still time. The cancelling of the 5 prior debates cut short important policy discussions and shortchanged ME voters. So, LET’s DEBATE costelloforsenate.com #MEpolitics

To reiterate, Maine’s US Senate race is not settled! ME’s DEM primary is next week. And I believe that I have the most fitting background, knowledge, and experience to defeat Senator Susan Collins and to help in advancing real, substantive change in Washington (costelloforsenate.com) #MEpolitics

Anything can, and often does, happen overnight in politics. Maine voters should rest assured that I, as a broadly knowledgeable and experienced Senate candidate, am fully committed to thoroughly and energetically advancing long-overdue, substantive CHANGE in Washington #MEpolitics

Strengthening US democracy, Step 1: eliminate the corrupting influence that MONEY has over our politics and government (e.g. actions: reverse bad SCOTUS decisions, ban dark $$$, strict donation limits, expand public financing, and mandate free media. Other steps @ costelloforsenate.com #MEpolitics

Climate change is real. Largely human caused and already an existential threat to many communities and livelihoods. To tackle climate change we must implement an aggressive, science-based plan to markedly curtail greenhouse gas emissions globally and pull carbon down from our atmosphere. #MEpolitics

Housing problem: Maine median incomes up only 50% over past decade; home prices up 110%, due to limited inventory and slow construction. Solutions: state & local permitting and reg reforms; boosted wages; more ME and fed $$$ for home construction and ownership; and lower interest rates #MEpolitics

Coffee and Conversation - Join me and my crew at 3:30PM in Biddeford on Saturday (5/30/26) for a cup of coffee and conversation at Time and Tide Coffee, 35 Maine Street. To RSVP: www.costelloforsenate.com/event-detail...

Canadian visits to Maine have fallen by more than 25%. A drop with severe repercussions for Maine’s tourism industry. With summer upon us it’s hard to see those numbers improving unless Trump alters his ill-tempered rhetoric and policies (He doesn’t care!). To fix, change Congress! #MEpolitics

It’s estimated that 1,049,454 Americans have died in wars spanning from Lexington and Concord to today. Each number represents a person who never came home, a family forever changed. All who sacrificed are honored today...

Costly War! Looks like the Trump Admin is being forced to accept a peace deal with Iran that’s likely to leave most involved, except Iran, in a strategically worse position than was the case after the JCPOA deal negotiated by the Obama Admin in 2015. The deal scrapped by Trump in 2018. #MEpolitics

The takeover of news outlets, like CBS, by billionaires are among the most insidious threats to American democracy. Money (greed) and disinformation are increasingly corrupting our politics and government and must be mitigated. Let’s start by electing pro-democracy leaders in 2026 #MEpolitics

I believe that I am the most qualified candidate to take on Senator Susan Collins in November and advance real change in Washington. #MEpolitics

USAID reduced poverty, food insecurity, and the spread of diseases globally, while promoting peace, democracy and economic development. It’s dismantling by the Trump Admin is hindering efforts to respond to an Ebola outbreak and has led to an increase in conflict across parts of Africa😡 #MEpolitics
